Explanation:

Step1: Convert hours to minutes

$6\ hr\times60\ min/hr = 360\ min$

Step2: Calculate total drops

$500\ mL\times10\ drops/mL = 5000\ drops$

Step3: Calculate infusion rate

$\frac{5000\ drops}{360\ min}\approx13.89\approx140\ drops/min$ (rounded to the nearest whole - number as per the options)

Answer:

140 drops/min
