Match the reaction to the type that best describes it.

A. C + 2H2 CH4

B. CO2 O2 + C

C. 2Cu + MnCl2 Mn + 2CuCl

D. NaBr + KF NaF + KBr

Combination

Decomposition

Double replacement

Single replacement

The correct matches would be as follows:

A. C + 2H2 = CH4

Combination

B. CO2 = O2 + C

Decomposition

C. 2Cu + MnCl2 = Mn + 2CuCl

Single replacement

D. NaBr + KF = NaF + KBr

Double replacement

Hope this answers the question. Have a nice day.
