Answer:(3) 1845
Explanation:-

Let be the four consecutive odd numbers are = X, X + 2, X + 4, X + 6.
According to the question,
(X + X + 2 + X + 4 + X + 6)/4 = 42

4X + 12 = 42 x 4
4X = 168 – 12
4X = 156
X = 156/4
X = 39
Therefore, the value of numbers B and D = 39 + 2 and 39 + 6
= 41 and 45
Thus, the product of B & D = 41 x 45 = 1845
