Hi Shikhar ,
Another good question buddy. +1 kudo for the same. Explanation
(A) increased by more than twice : Twice is an adverb and it cannot be an object of by which is a preposition and by requires a noun in place of an adverb.
(B) increased more than two times : When the number of degrees "increased more than two times," that means over the period of 1978 to 1985, it has gone up at least twice: maybe in 1980 and then in 1981. The other times, it has stayed steady or gone down.
(C) more than doubled : doubled is used correctly in the simple past and is correct.
D & E . incorrect use of tenses in both the cases.If this helps then award me a KUDO
If you like my post, Press +1 KUDO. It is the best way to say Thanks .
