Given:
- Seeta goes for a swim after a gap of every 2 days
- Geeta goes for a swim after a gap of every 3 days
- Both of them went for a swim together on 1st January

To find:
- When will they go for a swim together next?

Solution:
Let's find out the swim dates of Seeta and Geeta after 1st January.

Seeta's swim dates:
- 1st January
- 3rd January
- 5th January
- 7th January
- 9th January
- 11th January

Geeta's swim dates:
- 1st January
- 4th January
- 7th January
- 10th January

From the above dates, we can see that Seeta and Geeta will go for a swim together on the 7th of January, which is the common swim date for both of them.

Therefore, the correct answer is option D (13th January is incorrect as it's beyond the given dates).
