The question asks us to determine which day of the week the first February of the next year will fall on if the first March of the current year is a Sunday.

To solve this, we need to consider the number of days in each month and the leap year pattern. A leap year occurs every 4 years, except for years that are divisible by 100 but not by 400.

Since March has 31 days, April has 30 days, May has 31 days, and so on, the first February of the next year will be 335 days after the first March.

Since 335 days divided by 7 equals 47 weeks and 6 days, we can conclude that the first February of the next year will be 6 days after a Sunday.

Therefore, the correct answer is option 4: Monday.

Alert - The correct answer should actually be Option 3: Saturday. The provided answer does not take into account the leap year pattern, which affects the number of days in each year. As a result, the calculation is incorrect, and Option 3 is the correct answer.
