View answer and explanation

Correct option: C

0.01 \times {10^{ - 1}}

Option C (

0.01 \times {10^{ - 1}}

) is correct because the subtraction 0.99 - 0.989 = 0.001, which can be written as

0.01 \times 10^{-1}

. The result should have the same number of decimal places as the least precise number (0.99).
