    a) 65.74 ± 0.01

    b) 60.009 ± 0.001

    c) 66 ± 1

    d) 65.750 ± 0.001

    Explanation:

    When reporting results, scientist usually specify a range of values that they expect this "true value" to fall within. The most common way to show this range of values is: measurement = best estimate ± uncertainty

    Uncertainties are almost always quoted to one significant digit (example: ±0.05 s).

    Wrong: 34.3 cm ± 4.3 cm

    Correct: 34 cm ± 4 cm

    Always round the experimental measurement or result to the same decimal place as the uncertainty.

    Wrong: 1.237 s ± 0.1 s

    Correct: 1.2 s ± 0.1 s

    Therefore for to answer the question:

    a) 65.74 ± 0.01

    b) 60.009 ± 0.001

    c) 66 ± 1

    d) 65.750 ± 0.001

    I hope you find this information useful and interesting! Good luck!
