    B Length of the string Correct Answer Incorrect Answer
    C Amplitude of swing Correct Answer Incorrect Answer
    D Gravitational constant only Correct Answer Incorrect Answer

    Solution

    It does not depend on the mass of the bob or amplitude (for small angles).   A longer pendulum has a longer time period.   This principle is used in pendulum clocks.
