P = {12,16,20,24,28,32,36,40,44,48,52}

(1)

From the given restriction on numbers, there are more than one possible way

Q = {12,16,20,24,32,40,44,48,52}

Q = {12,20,24,28,32,40,44,48,52}

(2)

Not Sufficient

Q = {12,16,20,24,32,40,44,48,52}

Q = {20,24,28,32,36,40,44,48,52}

After combining both the options, there are multiple possible combinations, so answer - E

P = {12,16,20,24,32,40,44,48,52}

P = {12,16,24,28,32,40,44,48,52}
