Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -2.761\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COC(=O)c1c(C)n(-c2ccccc2)c2ccc(O)cc12
b) CCOc1ccc(-n2c(N)c(C(=O)NCc3ccco3)sc2=S)cc1
c) Cl.O=C(CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
Answer: a. COC(=O)c1c(C)n(-c2ccccc2)c2ccc(O)cc12
