Correct answer: C
Answer: 5 Mondays
Explanation: If 25 October is Thursday, go back 24 days to reach 1 October. Since 24 ≡ 3 (mod 7), the weekday shifts back 3 days: Thursday − 3 days = Monday. Thus 1 October is Monday.
List the Mondays in October: 1, 8, 15, 22, 29.
All these dates are within the 31 days of October, so there are five Mondays.
Therefore the number of Mondays in that October is 5.
