Explanation:

Let’s break this down:

- The question is: Is it Friday today?

- Statement I: February 21 of this year was a Wednesday. So, if we know the exact date today, we could count days from Feb 21 to today to check what day it is.

- Statement II: Today is March 18. This gives us the date, but tells us nothing about the day of the week.

Option breakdown:

- Option 1: We could answer with one statement but not the other.

- If we just know Feb 21 is Wednesday, but not today’s date, we’re stuck.

- If we just know today is March 18 but nothing about Feb 21, also stuck.

- Option 2: Either statement alone lets you answer. That’s just not true here.

- Option 3: Both statements together work, but neither alone does.

- Here’s the catch: If we know Feb 21 is Wednesday and today is March 18, we can count the days and nail down the day of the week for March 18. So, together, yes, you get your answer.

- Option 4: Not even with both together. That’s just not true—you can answer with both.

So, the correct answer is Option 3.

Put simply:

- Both statements together let you answer the question.

- Separately, each is useless.
