-------------------------------------------------------------------
I actually got this question right but I need some clarification on why "causing flames to spread more quickly" is preferred to "making flames spread more quickly?
I observe that making has been used in the original sentence already so to use making again would be redundant. But consider the following....

For example:
A fire in an enclosed space burns with the aid of reflected radiation that preheats the fuel, causing/making the flames spread more quickly.

I was actually also expecting "making flames spread". I think "making flames spread" would have been a better choice if it were available. It maintains parallel structure just as "causing flames to spread" does and it's more concise.

Since it's not one of the choices, we're left to pick the best of the options available.
