Design the Logic circuit with Minimum no. Of Gates in which four Inputs A,B,C and D .A is MSB and output is Y.The Output is high when a four bits in odd parity

Design a circuit with four Inputs A,B,C and D .A is MSB and output is Y.The Output is high when a four bits in odd parity(means no. Of one's in four bit is odd).
Example shown below

Design the Circuit using minimum no. Of gates.
