Explanation:

​​​​​​​

Let the number of people liking

exactly 1 game = a (all orange areas together) = 90
exactly 2 games = b (all green areas together)
all three games = c (blur area)
none of the three games = n

⇒ n + a + b + c = 130   
⇒ n + b + c = 40 ...(1)

Also, When we add those who like Cricket (60), Football (45) and TT (45), we add 'a' once, 'b' twice and 'c' thrice.
∴ a + 2b + 3c = 60 + 50 + 45
⇒ 2b + 3c = 65   ...(2)

Now, to maximise 'b + c', we should maximise the variable with lesser coefficient and to minimise 'b + c', we should maximise the variable with higher coefficient.

Here, we need to maximise 'b + c', hence we will maximise 'b' and minimise 'c'.
For, 'b' and 'c' to be integers, least value 'c' can take is 1.

Hence, 2b + 3 = 65
⇒ b = 31

∴ Maximum possible value of 'b + c' = 31 + 1 = 32.

Hence, option (b).
