([a-zA-Z]{3}\d{3}) tested & verified using regex101. This is the result: {3} matches the previous token exactly 3 times a-z matches a single character in the range between a (index 97) and z (index 122) (case sensitive) A-Z matches a single character in the range between A (index 65) and Z (index 90) (case sensitive) \d matches a digit (equivalent to [0-9]) {3} matches the previous token exactly 3 times

a-zA-Z = matches any 3 letters, it will be either upper or lowercase followed by d{3} = 3 random digits The result from this regex pattern could be: XYZ789 , MNO345 etc

I think given answer is correct. for the first box, they said 3 alphabetical characters i.e you can have these combinations of letters : ABC, bcE, cdf, ... so fisrt answer is [a-zA-Z]{3}. Now for the second one, they said followed by three digits it's the same thing for the alphabetical letters you'll have a combination of three digits: 123, 135, 911,... so the second box is \d{000-999}. so the full answer is [a-zA-Z]{3}\d{000-999.

\d{000-999} doesn't match using regex101, it would have to be \d{000,999} instead for option D to be correct
