By De Morgan's Law Y=bar(A)+bar(B+CD) is equals to

1. bar(A)bar(B+CD)
2. bar(A)+bar(B)(CD)
3. bar(A)+bar(B)bar(CD)
4. bar(A)bar(B)bar(CD)

By DE Morgan's Law Y=bar(A(B+CD)) is equals to

1. bar(A)bar(B+CD)
2. bar(A)+bar(B+CD)
3. A+bar(B+CD)
4. bar(A)+(B+CD)

System in which Y is high for A input is high and simultaneously either B input is high or C and D both are high is represented as

1. Y=A(B+CD)
2. bar(Y)=A(B+CD)
3. bar(Y)=A(2+CD)
4. bar(Y)=AB+CD

By De Morgan's Law Y=bar(A)+bar(B)bar(CD) is equals to

1. bar(A)bar(B+CD)
2. bar(A)+bar(B)(bar(C)+D)
3. bar(A)+bar(B)(C+D)
4. bar(A)+bar(B)(bar(C)+bar(D))

System in which Y will be high if A is low or B and C are both low is represented as

1. Y=A+BC
2. Y=ABC
3. Y=A+bar(BC)
4. Y=bar(A)+bar(BC)
