From a quick look , it seem that ans is B (1 and 2 is correct)? It might be faster if you can post the corresponding answers for your selected questions.

For propane, two possible radicals can be formed. The unpaired electron could be on the 1st ( CH2CH2CH3) or 2nd carbon (CH3CHCH3)

So we can have some combinations for the termination step.

Option 1, formed by CH2CH2CH3 + CH3CHCH3
Option 2, formed by CH3CHCH3 + CH3CHCH3

In short,
The compounds in 1 and 2 are made from C3H7 free radicals. The compound in 3 is made from C2H5 and C4H9 free radicals.

Welcome!
Copy Paste, as this all wasn't fitting in one comment, so Just posted one point in one comment, so that it's easy to get it understand, or it can easily be grasped.
