Answer:
Option B = 60,600 mg (correct option)
Explanation:
First of all we will have an idea which numbers are consider as significant.
1 = All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
2= Leading zeros are not consider as a significant figures. e.g. 0.02 in this number only one significant figure present which is 2.
3= Zero between the non zero digits are consider significant like 105 consist of three significant figures.
4= The zeros at the right side e.g 3400 are also significant. There are four significant figures are present.
In given options, Option A 60.6 mg have 3 significant figures.
Option B have 5 significant figures.
Option C have 4 significant figures.
Option D have 3 significant figures.
Thus option b is correct option which have more significant figures.

The substance used for decolorization of undesirable color in a crystalline substance is powdered animal charcoal
Decolorization is the process of eliminating organic contaminants with vivid colors from the sample mixture.
Unwanted colors are removed by boiling the item with a suitable amount of powdered animal charcoal in a hot solution that has been filtered so that the charcoal may absorb the colors. The charcoal is a finely divided carbon.
