    The answer is B. thus 7.4*10^9

    Step-by-step explanation:

    This is because, in scientific notation, we deal with numbers which are in the standard form

    And from alt A-D, only the alt B is in the standard form. the rest are not in the standard form hence cannot be considered them as written In scientific notation.
