When marking brand names or logos, the symbol you see tells you the legal status of that mark. An unregistered trademark is shown with TM. It signals that the owner claims rights to the mark in commerce, but it may not be officially registered yet, so the protection isn’t as strong as a registered mark. The circled R indicates a registered trademark, which means formal registration has been completed. The copyright symbol signals protection for original works, not branding marks. So the symbol that best communicates an unregistered trademark is TM.

Pixel dimension is the number that specifies how many pixels make up the image in width and height, i.e., the image’s size in pixel units. Saying an image is 1920 by 1080 tells you there are 1920 pixels across and 1080 pixels down, which is exactly what describes its size in pixels. Resolution is related but can be broader, sometimes signaling detail or display density rather than the exact pixel grid. Color depth refers to how many bits are used to represent each pixel’s color, not how many pixels there are. Aspect ratio is about the proportional relationship between width and height, not the pixel count.

Sample rate tells you how often the audio signal is sampled per second when converting analog sound to digital. It is the number of samples taken each second, typically measured in kilohertz. Higher sample rates capture more detail and can represent higher frequencies, following the idea that you can accurately reproduce frequencies up to half the sampling rate. That’s why increasing the rate improves quality but also increases file size and processing needs. The other options refer to different concepts: color depth is about images, compression ratio is about how much data is reduced, and the number of channels is about how many separate audio paths exist. So the description that fits is that it’s the number of samples per second, with higher rates increasing quality and file size.

Being informed about how personal data is handled is essential. Data subjects have a right to clear information about what data is collected, why it’s processed, and how long it’s stored. This transparency lets individuals understand the full lifecycle of their data and assess the privacy risks and controls they might want to exercise. The option that mentions collection, use, and storage captures this complete picture—the storage aspect is important because it relates to retention and eventual deletion, not just how data is initially collected or used. The other ideas are less accurate in capturing the full right: simply knowing about collection and use omits how long data is kept; a blanket right to refuse data sharing isn’t a universal guarantee and depends on context; and data portability is about obtaining a copy of one’s data and moving it to another controller, not about sharing decisions in general.
