The number of full-time professional organizers in Denver, Colorado, increased by more than thrice from 1996 to 2004.

(A) increased by more than thrice
(B) increased more than three times
(C) more than tripled
(D) was more than tripled
(E) had more than tripled
_________________

Can anyone explain the difference between B and C?
_________________

There is not much difference in usage of thrice,three times,or tripled
The main crux is how to convey intention of sentence in less words.

More than tripled is better than more than thrice because of words

Here more than tripled use less words to convey intended meaning

So C is correct

D and E are wrong as was and had are not required in sentence

Construction wise b is correct.
But the same intention is expressed using few words in option C

So C is better choice than B

Give kudos if this helps

------>The main comparative subject is "the number of full-time professional organisers", so the correct comparison should be "3 times greater than".

(A) increased by more than thrice--->it's obviously wrong
(B) increased more than three times---->Incorrect form of comparison.
(C) more than tripled
(D) was more than tripled---->Incorrect meaning cause it uses passive form.
(E) had more than tripled--->Incorrect meaning cause it uses passive form.
---->The answer is C

Hi gvij2017 and Kunal112,

Tripled is a verb there. The more than before tripled just means that this was a >3x increase (without the more than, it would have been 3x).
