The operation which is commutative but not associative is:

1. AND
2. OR
3. EX-OR
4. NAND

'communicative' should be 'commutative'

$Remark:$
1)Every logic gate follows Commutative law.
2)AND,OR,Ex-OR,EX-NOR follows Associative law also. NAND,NOR doesnt follow Associative law.

Its good to remember-
1)Every logic gate follows Commutative law.
2)AND,OR,Ex-OR,EX-NOR follows Associative law also. NAND,NOR doesnt follow Associative law.

commutative law: A operator B = B operator

associative law: A operator (B operator C) = (A operator B) operator C

EX-NOR is associative...

Ans is D you can varify it like  ((AB)'C)' = (A(BC)')' are not equivalent for input 011.
