Explanation:

1. Check each option against the given pattern attr(optional) while ( condition ) statement:

• "condition is mandatory": The pattern shows condition has no (optional) label, so it is required. This is true.
• "statement is optional": The pattern shows statement has no (optional) label, meaning it is mandatory, not optional. This is false.
• "The following syntax is correct: while (x == 0) count++": This matches the pattern (no optional attr, valid condition, valid single statement). This is true.
• "attr is optional": The pattern explicitly labels attr as (optional). This is true.
