Explanation

In Cisco Unity Connection restriction tables, two wildcard characters are used for digit matching: '?' matches exactly one digit (0–9), and 'X' also matches exactly one digit (0–9). Both 0????????? (choice B) and 0XXXXXXXXX (choice C) define patterns that match any 10-digit number beginning with 0: the leading '0' is a literal match, and the nine wildcard characters (? or X) each match exactly one additional digit, giving exactly 10 digits total. These two patterns together cover the requirement to block 10-digit numbers starting with 0, which includes international numbers dialed with a leading 0 access code. Choice A (9!) and D (9*) would match numbers starting with 9 (outbound PSTN access codes), which is not what is required. Choice E (0-9*) is not valid Unity Connection restriction table syntax.
