Quizplus · Accepted Answer

To divide two numbers in scientific notation, we need to divide their coefficients and subtract their exponents. 
So, $$\frac { 1.44 \times 10 ^ { - 13 } } { 1.2 \times 10 ^ { 3 } } = \frac{1.44}{1.2}\times10^{-13-3} = 1.2\times10^{-16}$$
Therefore, the answer is choice C.
