    Answer: (2) 91
    Explanation:-
    Let the two consecutive odd numbers are X , X + 2.
    According to the question,
    (X ) x (X + 2) = 8463
    X2 + 2 X = 8463
    X2 + 2 X – 8463 = 0
    X2 + 93 X – 91 X – 8463
    X (X + 93) – 91 (X + 93) = 0
    (X + 93) (X – 91 ) = 0
    X – 91 = 0
    X = 91
    Then, X + 2 = 91 + 2 = 93
    Hence, the smallest number is 91.
