Explanation:

To solve this problem, we need to find out the day of the week after 52 days from today. We can use the concept of modular arithmetic to find the day of the week.

Modular arithmetic:

Modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" upon reaching a certain value called the modulus. For example, if we are using a modulus of 7 (which is the number of days in a week), then after 6 days, we "wrap around" to the first day of the week. This is because 7 mod 7 is 0, which means that 7 is equivalent to 0 (mod 7).

Using modular arithmetic, we can find out the day of the week after a certain number of days.

Step-by-step solution:

1. Today is Thursday, which is the fourth day of the week. We can represent this as 4 (mod 7).
2. After 52 days, we need to find out the day of the week. We can represent this as (4 + 52) (mod 7).
3. Simplifying, we get (4 + 52) (mod 7) = 56 (mod 7).
4. Since 56 mod 7 is 0, we can say that after 52 days, we "wrap around" to the first day of the week, which is Sunday.
5. However, we need to find out the day of the week after 52 days from today. Since today is Thursday (which is the fourth day of the week), we need to add 4 more days to Sunday.
6. Adding 4 days to Sunday, we get Monday as the day of the week after 52 days from today.

Therefore, the correct answer is option (c) Monday.
