    Answer:

    The correct option is (a).

    Explanation:

    We need to find the product of given numbers.

    First number = 29.5

    Second number = 240

    Product of two numbers = 29.5 × 240

    = \dfrac{295}{10}\times 240

    Zeroes from numerator and denominator get cancelled.

    So,

    =295\times 24\\\\=7080

    Hence, the correct option is (a).
