Select the number from among the given options that can replace the question mark (?) in the following series.

3, 9, 21, 45, ?

Given: 3, 9, 21, 45, ?

Logic: (Previous number $$\times$$ 2) + 3 = Next number in given series.

3 × 2 = 6, 6 + 3 = 9

9 × 2 = 18, 18 + 3 = 21

21 × 2 = 42, 42 + 3 = 45

Similarly, 

45 × 2 = 90, 90 + 3 = 93
