Explanation:

Let’s walk through this together:

- Event setup:

6 events, 3 months (May, July, September), dates are 9th and 13th each month.

- Key points from clues:

- *A* is on a prime date (only 13 is prime here) in a month with 31 days (so not September, which has 30 days—only May and July count).

- Two events between *A* and Uttarakhand.

- Kerala is right after Uttarakhand.

- Same number of events before *C* as after Kerala (so *C* is event 2, Kerala is event 5).

- One between *C* and Rajasthan.

- No event between Rajasthan and *E*, but *E* isn’t Rajasthan.

- Tripura before Punjab.

- *C* is not Tripura.

- *D* after *B*, but before *F*.

- Only one event in Karnataka.

Now, statement checks:

1. Event B not in Punjab

- Let’s check placement: By the sequence needed, *B* lands before *D*, but Tripura is before Punjab, and Punjab is near the end. Feasibly, *B* cannot fit Punjab’s slot without breaking constraints. So this is correct.

2. Kerala on 13th September

- Kerala comes right after Uttarakhand and is fifth. Only the last two slots are left for Kerala (either 13th September or 9th September). Since *C* must be the second event and events are indexed by date/month, Kerala does indeed fall on 13th September. This is correct.

3. C wasn't the first event of the year

- *C* is the second event (as many events before as after Kerala, Kerala = 5th, so *C* must be 2nd). True – C was not the first.

Which options match?

- 1 = correct

- 2 = correct

- 3 = correct

So the right answer is:

Option 4: All 1, 2, and 3 are correct

Here’s what really matters:

- Every statement listed is actually correct.

- Option 4 is the answer that ticks every box—so go with that one.
