The 2nd ball have the monster.

so contradicting statement

Assume 2nd statement is true and 1 and 3 are False

1st  ball  have the monster.

2nd ball  has the monster.

2nd ball  have the monster.

so contradicting statement

Assume 3rd statement is True  and 1st and  2nd are false.

2nd ball does not have the monster

Hence 1st Ball have the monster.

so 1st ball should be picked.
