(B) is different than any terrestrial lava’s, containing -- wrong - "different from" should be

(C) is different from that of any terrestrial lava; they contain - I have doubt about pronoun reference in this choice, see below.

(D) differs from any terrestrial lava in containing - wrong should be "that (composition) of any terrestrial lava"

(E) differs from that (composition) of any terrestrial lava’s (composition), containing - wrong

Tektites, which may have been propelled to Earth from lunar volcanoes, are much like the volcanic glass obsidian, but their chemical composition is different from that of any terrestrial lava; they (Tektites) contain far less water than obsidian does and none of its (lava) characteristic microcrystals.

Please correct me if I am wrong and kindly comment pronoun reference.
