If tomorrow is Sunday, what day of the week will be 121 days from today?​

Given: Tomorrow is Sunday, So today must be Saturday.

The days of the week repeat every 7 days.

To find the day after 121 days.

121÷7=17 → remainder 2

The remainder 2 tells us that the day will be 2 days ahead of today (Saturday).

Saturday + 2 days = Monday

Thus, correct option is (d).
