Task: Answer the multiple-choice question.
Query: Which drug exhibits a -25.490\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) C=CCn1c(COc2ccccc2)nnc1SCc1ccc(C#N)cc1
b) O=C(COC(=O)c1ccncc1)Nc1cc(Cl)ccc1Cl
c) O=C1CC(c2ccccc2)CC(O)=C1C=NCCN1CCNCC1
d) Cc1ccnc(SCc2cc(=O)c(OC(=O)c3ccco3)co2)n1
Answer: a. C=CCn1c(COc2ccccc2)nnc1SCc1ccc(C#N)cc1
