Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.169% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1cc(/C=C/C(=O)N2CCN(Cc3ccccc3)CC2)cc(OC)c1OC
b: Cc1cc(C)c(C#N)c(SCc2ccccc2F)n1
c: Cc1ccc(S(=O)(=O)NCC2CCC(C(=O)N3CCC4(CC3)OCCO4)CC2)cc1
Answer: b. Cc1cc(C)c(C#N)c(SCc2ccccc2F)n1
