Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 15.504\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C1c2cccc(Cl)c2C(=O)N1c1ccccn1
b) O=S(=O)(Nc1cccc(-c2cn3cccnc3n2)c1)c1ccc(Cl)cc1
c) COc1ccc(CNC(=O)CN(C(=O)c2csnn2)c2cnc3ccccc3c2)cc1
Answer: a. O=C1c2cccc(Cl)c2C(=O)N1c1ccccn1
