Given for the triangle OPQ

The angle opposite to the side PQ ⇒∠O
The angle opposite to the side QO ⇒∠P
The angle opposite to the side OP ⇒∠Q
The longest side will be opposite to the greatest measure of angle
so, we will arrange the sides from the highest to the least

So, the arrange of the angles from the greatest to the least will be:

So, the answer will be the first option
