Free radical substitution

Which species is produced in a propagation step during the reaction of propane with an excess of chlorine in the presence of UV light?
A. Hydrogen free radical
B.C3H5Cl
C.C3H6Cl2
D.C6H14

im unsure on this question as i would have thought the propagation step would result in C3H7Cl. It has been a while since ive done this but im almost certain thats what it should be. Please explain thanks. There could be a possibility the question is wrong though.

Answer is C btw

At no point is H+ produced

During propagation step 1, Cl. attacks, pulling off an H forming molecular HCl, not ions.

I crossed it out, it's meant to just be HCl

I may have been willing for forgive you, but you wrote H+ again in the last sentence.
This stuff haunts me. And I’m repeating so I can’t hide from any of it 😬
