Sure, let's simplify the expression step by step and write the answer in scientific notation.

The expression is:
\[ 0.6 \times (6.5 \times 10^{-5}) \]

First, let's multiply the numeric values:
\[ 0.6 \times 6.5 = 3.9 \]

Next, we consider the exponent part:
\[ 10^{-5} \]

So, combining these results:
\[ 0.6 \times 6.5 \times 10^{-5} = 3.9 \times 10^{-5} \]

Therefore, the simplified expression in scientific notation is:
\[ 3.9 \times 10^{-5} \]

So, the correct answer is:
\[ 3.9 \times 10^{-5} \]
