They secrete carbon dioxide that combines with water on the rocks and dissolves the minerals in the rocks.

B.
They secrete chemicals that allow them to ingest minerals in the rocks.

C.
They secrete acids that dissolve the minerals in the rocks.

D.

chemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals (also known as biological weathering) in the breakdown of rocks, soils and minerals. The main agent responsible for chemical weathering reactions is water and weak acids formed in water. Plant roots can produce weak acids that directly act on rocks. 

The most common forms of biological weathering are the release of chelating compounds (i.e. organic acids, siderophores) and of acidifying molecules (i.e. protons, organic acids) by plants so as to break down aluminium and iron containing compounds in the soils beneath them. Decaying remains of dead plants in soil may form organic acids which, when dissolved in water, cause chemical weathering
