comma doing, pls, help

[thanghnvn]

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging,// which is the removal of only selected trees, as well as surface fires, burning// down individual trees but do not denude the forest.

A. which is the removal of only selected trees, as well as surface fires, burning
B. which removes only selected trees, or surface fires that burn
C. which removes only selected trees, along with surface fires that burn
D. removing only selected trees, or surface fires, burning
E. removing only selected trees, as well as surface fires that burn

in above sentence, the choice D is wrong because of "coma removing" and "comma burning.."

why.
