The Boolean expressionY = A B C + A B C D + A B C D + A

1. Y = A B C D + A B C + A C D
2. Y = A B C D + B C D + A B C D
3. Y = A B C D + B C D + A B C D
4. Y = A B C D + B C D + A B C D

Given expression Y = A B C D + ABCD + AB CD + ABC D
or Y = B CD( A + A) + ABCD + ABC D
or Y = ABCD + B CD + ABC D
