    Answer:

    option b

    Explanation:

    according to Ohms law

    Voltage, V = Current I × Resistance, R

    V = IR\\\\where\\\\R = \frac{V}{I}

    from the above ohms law relation and making R the subject

    let assume that voltage V is constant.

    we can conclude that

    R is inversely proportional to current I

    that is

    R \alpha \frac{1}{I}

    this means that as resistance, R increases in a circuit, current, I decreases

    also

    As R decreases I increases
