I think it's D, because

the proposal states that methan should be burned, which would yield energy, instead of warming up the atmosphere when rising up from landfills, but the objection counters that burned methan becomes carbon dioxide, another greenhouse gas, thus would in fact bring no improvement to the situation.

But if carbon dioxide is less contributing to the warmhouse effect, as D states, the proposal would be strengthened.

This one is tricky, if one overlooks the actual meaning of C. Therein it is stated that methan ( or the energy it can provide) would be a substitute for a fuel, which does not contribute to the greenhouse effect.

Yes , D IMO.

Only D reduces the sum of gases - offcourse we assume that equal amount of CO2 is released - which is less effective in (global) warming
