Select the number from among the given options that can replace the question mark(?) and complete the pattern.

Multiplying the opposite numbers in the first diagram we get $$5\times\ 2=10\ \&\ 6\times\ 3=18$$
Adding them, we get the number in between, which is 28

Multiplying the opposite numbers in the second figure, we get $$4\times\ 4=16\ \&\ 3\times\ 8=24$$
Adding them, we get the number in between, which is 40

Similarly, for the third figure, by multiplying the opposite numbers, we get $$6\times\ 4\ =24\ \&\ 6\times\ 5=30$$
Addin them, we should get the number which should come in between, which is 54

Therefore, Option A is the correct answer.
