Factor a square root of 14 out of every expression to get:

\sqrt{14}*(\sqrt{4}-1+\sqrt{9)

\sqrt{14}*(2-1+3)

4*\sqrt{14}

Thus, the expression is equal to four times the square-root of 14.  The second answer is correct.

<h3>What is unit conversion?</h3>

Unit conversion is a multi-step process that entails multiplying or dividing by a numerical factor, selecting the correct number of significant digits, and then multiplying or dividing by another numerical factor.

The unit conversion will be done as:-

1 km  =  1000 meters

0.0150 Km = 0.0150 x 1000 meters

0.0150 Km = 15 meters

Therefore the correct answer is option C which is 15 meters.
