The answer is D

the formula you need to use is Q=mc(delta)t the delta is usually written as a triangle

rearrange this to make c the subject as this is the specific heat capacity

so you get c=Q/(m*tempchange)

delta t means temp change btw

plug in you values so 550/(6*25)

and you get 3.666666

to 1 decimal place = 3.7
