Explanation / Answer

A and B are correct!

C)

copper(II) nitrate and sodium sulfate

Cu(NO3)2 + Na2SO4(aq) --> 2NaNO3(aq) + CuSO4(aq)

note that CuSO4 is very soluble, so there is NOREACTION!

D)

strontium nitrate and sodium sulfate

SrNO3 + Na2SO4 --> NaNO3 + SrSO4

same case as before, Sr and Na are IA family metals, those will remain in ionic state in aquous solution

so NOREACTION
