c.  $1.256\times 10^{-6}A$

Explanation:

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example : 5000 is written as $5.0\times 10^3$

a. 10130 Pa to 2 decimal place is written as $1.01\times 10^{4}Pa$

b. $978.15ms^{-2}$ to 1 decimal place is written as $9.8\times 10^{2}ms^{-2}$

c.  $0.000001256A$ to 3 decimal places is written as $1.256\times 10^{-6}A$
