D) A3J7 is the answer, no doubt. It's the only one that could be the license plate of a getaway car.

I'm a bit confused by this question. What exactly counts as "alphanumeric"? Is it just any mix of letters and numbers, or does it have to be a specific format? I want to make sure I understand before I answer.

I got this! Option D is the only one that contains alphanumeric values. The rest are just numbers. Easy peasy.

Okay, let me think this through. Alphanumeric means it has to have both letters and numbers, so I'm going to eliminate the first three options since they're just numbers. That leaves me with option D, which has both letters and numbers.

This looks like a pretty straightforward question. I'd start by quickly scanning the options and identifying which ones contain both letters and numbers.
