Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 16.878% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=S(=O)(c1ccc(O)cc1)c1ccc(O)cc1
b) O=C(COC(=O)CSc1ccccc1)NNC(=O)c1ccc([N+](=O)[O-])cc1
c) COc1cccc(/C=N/n2c(COc3ccccc3)n[nH]c2=S)c1OC
Answer: a. O=S(=O)(c1ccc(O)cc1)c1ccc(O)cc1
