Students in a science class observed that when a strip of Magnesium (Mg) metal was placed in a test tube containing Hydrobromic acid (HBr), the Magnesium began to bubble as hydrogen gas and Magnesium Bromide are formed. Which of the following choices show both the correctly balanced equation and identify the type of reaction?

A. Mg+2HBr →H2+MgBr2 (synthesis)

B. 2Mg+HBr →H2+2MgBr2 (decomposition)

C. Mg+2HBr →H2+MgBr2 (single replacement)

D. Mg+2HBr →2H2+MgBr2 (double replacement)

Pls answer correctly I really need a good grade on this, I'll mark brainliest.
