Could someone check if these are right?

Which of the following equations represent redox reactions?

a) 2KNO3(s) –> 2KNO2(s) + O2(g)
b) H2(g) + CuO(s) –> Cu(s) + H2O(l)
c) NaOH(aq) + HCl(aq) –> NaCl(aq) + H2O(l)
d) H2(g) + Cl2(g) –> 2HCl(g)
e) SO3(g) + H2O(l) –> H2SO4(aq)

I chose A, B, and D.

If I am wrong, could someone please explain. Thanks
Good luck with AP Chem tomorrow
