Right Basket.
Reason 1 : A venomous snake usually is quiet and patient while attacking its prey, trying to lure their prey into their boundary before making any sudden movement. So, logically the snake will not make any noise or a mess of its surroundings, in other words, the basket containing the snake will be clean and still as a rock. So, right basket is my guess. (The left one is too messed up to be the right choice)
Reason 2 : Why right basket? Because the middle one is too obvious. Usually in a game the actual answer is jumbled up. SO, judging by that, the correct basket must be something that is not that obvious to the viewer. In this case, the right basket.
