Which committee would be responsible for legislation regarding acquiring alternative fuel sources from us lands?
a) committee on commerce, science, and transportation.
b) committee on the environment and public works
c) committee on energy and natural resources
d) committee on appropriations

I'm making the inference that it would be C) because a committee that deals with energy and natural resources would be the most likely to make and oversee legislation of obtaining alternative fuel sources for energy and from things in our environment (my second thought would be B), but C) seems to be a better fit).

Your answer is b , public works
