- B attends the seminar on 5th January.
- Four people attend between H and A.
- A attends just before G.
- One person attends between G and E.
- D attends after H, and three people separate F and D.
- C doesn't attend in February.

Let's construct the sequence:

1. B - 5th January (given).
2. The next possible position for H is 11th January or 5th February.
3. If H is on 5th February, then A will be on 11th March (4 people after).
4. Hence, G will be on 11th March.
5. Then E takes 5th March (1 between G and E).
6. Since F is linked with D with 3 between, try placing F on 5th April and D on 11th April.
7. Since C is not in February, the only date left is 11th February.

This satisfies all conditions. Hence, **G attends the seminar in April**.

- ✅ **Correct Answer is: Option 3: G**
