a. 3Sr(NO3)2(aq) + Fe2(SO4)3(aq) ===> 3SrSO4(s) + 2Fe(NO3)3(aq)
b. SrSO4
c. Sr is above Ba in the Periodic Table. BaSO4 is one of the most insoluble salts known. So SrSO4, while more soluble than BaSO4, is itself not very soluble.

3Sr(NO3)2 + Fe2(SO4)3 --> 3SrSO4 + 2Fe(NO3)3
ppt = SrSO4
Standard rule of ppts that you have to memorize...certain sulfates are relatively insoluble and those are given to you in a list to memorize. You could as well resort to the Ksp of SrSO4 and if below a semi-defined number, it will precipitate.
