Answer:  Option 'B' is correct.
Step-by-step explanation:
Since we have given that 
[3.2] [2.7] [2.9] [4.8]
Since they are all of greatest integer functions i.e. 
f(x) = [x]
It is known as greatest integer function whose value is always less than or equal to 'x'.
So, [3.2]=3
[2.7]=2
[2.9]=2
[4.8]=4
so, we can see that [2.7] and [2.9] is a equivalent pair.
Hence, Option 'B' is correct.
