A. 0
B. 1
C. 2

Comprehensive and Detailed In-Depth
The regular expression 100.$ can be broken down as follows:
100: Matches the exact sequence of digits "100".
. (dot): Represents any single character.
$: Indicates the end of the line.
Therefore, the pattern 100.$ matches any four-character sequence that starts with "100" and ends with any single character.
1000 (A): Matches because it has four digits, starting with "100" and ending with "0".
1001 (B): Matches because it has four digits, starting with "100" and ending with "1".
10000 (C): Does not match because it has five digits.
100 (D): Does not match because it only has three digits.
