    C. 3.5 * 120

    Explanation:

    The correct complete question should be with these options

    a) 14 x 30

    b) 7 x 60

    c) 3.5 x 120

    d) None of these

    Let's consider simple mental calculation of all the options one after the other

    A. 14 x 30

    = 14x3x10

    =42x10=420 (simple 3 steps)

    B. 7x60

    =42x10 = 420 (simple 2 steps)

    C. 3.5x120

    =3x120+120x0.5

    =360+60=420 (complex steps)

    The correct answer is C because it involves multiple complex steps than the other options. It easier mentally break numbers up into smaller and easier pieces of integers than working with decimals.
