C! you be conscious of that H2 is between the products simply by fact it relatively is a unmarried alternative reaction and hydrogen is a diatomic gas. So this removes b and d. then you definitely seem to confirm which one is balanced. c has 2 Als on the two facets, 6 Hs on the two facets, and 6Cls, meaning it relatively is balanced. A has one Al one the two facets, yet then has 3 Hs on the reactant part and 6 Hs on the product! meaning it is not balanced. C is your answer :)

1. 2Al + 3H2SO4 --> Al2(SO4)3 + 3H2
2. CuSO4 + Pb(NO3)2 ---> PbSO4 + Cu(NO3)2
3. 2Cu + O2 --> 2CuO
(if you don't understand how these work, you really should get some tutoring)

2 Al + 3 H2SO4 ----> Al2(SO4)3 + 3 H2
CuSO4 + Pb(NO3)2 ------> PbSO4 + Cu(NO3)2 (presuming it is copper (II) and lead (II))
2 Cu + O2 ----> 2 CuO

2Al + 3 H2SO4 -------- Al2(SO4)3 +3 H2
CuSO4 + Pb(NO3)2------- Cu(NO3)2+PbSO4
4Cu + O2 --------2 Cu2O

2Al+ 3H2So4= Al2(so4)3+ 3H2
Cuso4+2PbNO3 = 2PbSO4+ Cu(NO3)2
4Cu+O2 = 2Cu2O
Hope its all ok with the balance but double check it.
