1 mg = 1000 mcg

To convert 200 mcg to mg, we divide by 1000:
200 mcg / 1000 = 0.2 mg

Next, we can use the strength of the medication to determine how many milliliters to give:
0.1 mg/ml = 1 ml/10 mg

To give 0.2 mg of atropine sulfate, we need to administer:
0.2 mg x (1 ml/10 mg) = 0.02 ml

Therefore, the answer is D) 2 ml.
