The expression is AB'CD + ABC'D + ABCD'.

AND gate-I is for the expression AB'CD;inverter-1 is connected to i/p B.

AND gate-II is for the expression ABC'D;inverter-2 is connected to i/p C.

AND gate-III is for the expression ABCD';inverter-3 is connected to i/p D.

For adding all these 3 expressions ,V need one OR gate.

So totally the expression needs 3 AND gate, 3 inverters, 1 OR gate.
