It's answer will be option A.
As in option A, both statements can not be true at the same time.
In option A, first statement is that the card drawn has odd number and second statement is card drawn is 10, which can not be possible at the same time.
In option B, both statements can be true at the same time.
In option B, first statement is that the card drawn has an even number and second statement is card drawn is 4, which can be possible at the same time.
In option C, both statements can be true at the same time.
In option C, first statement is that the card drawn has an even number and second statement is card drawn is 8, which can be possible at the same time.
In option D, both statements can be true at the same time.
In option D, first statement is that the card drawn has a number which is multiple of 3 and second statement is card drawn is 6, which can be possible at the same time.
So, the events of option A are mutually exclusive.
