Task: Answer the multiple-choice question.
Question: Which drug exhibits a -32.634% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CCCOc1ccccc1)N1CCN(c2ccccc2)CC1
[b] COCC(=O)NCCNc1nc2ccc(C)cc2cc1C
[c] CNC(=O)/C(C#N)=C/c1c(F)cccc1Cl
[d] CCOCCCNC(=O)C(NC(=O)CNC(=O)c1ccccc1)c1ccc(C)cc1
Answer: a. O=C(CCCOc1ccccc1)N1CCN(c2ccccc2)CC1
