Explanation:

Let’s break it down tribe by tribe:

- Naga: Traditionally, some Naga communities practiced polygyny, though it’s much less common now.

- Gond: Polygyny has been observed among the Gonds, especially in the past.

- Baiga: The Baigas are also known to have practiced polygyny.

- Todas: Traditionally, the Todas are known for polyandry (one woman, several men), not polygyny.

Now, let’s check your options:

1. 1, 2, 3 — Naga, Gond, Baiga

2. 2, 3 only — Gond, Baiga

3. 1, 3, 4 — Naga, Baiga, Todas

4. 1, 2, 3, 4 — all four tribes

Here’s the thing: Todas are famous for polyandry, not polygyny. So option 4 and 3 are out. Option 2 misses the Nagas, who also practiced polygyny. That leaves Option 1: 1, 2, 3 as the correct choice.

Option 1: 1, 2, 3 is correct.
