Task: Answer the multiple choice question.
Query: Which drug exhibits a -10.860\% 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(SCc2c(C(=O)OC)sc(N)c2C(=O)OC)nnc1-c1ccc(Cl)cc1
[b] COCCN(C(=O)c1csnn1)C(C(=O)NC1CCCC1)c1ccc(C)cc1
[c] C=CCNC(=O)c1ccc(OC)cc1
[d] Cc1cccc(C)c1NC(=O)COC(=O)c1c2c(nc3ccccc13)/C(=C\c1ccc3c(c1)OCO3)CCC2
Answer: a. C=CCn1c(SCc2c(C(=O)OC)sc(N)c2C(=O)OC)nnc1-c1ccc(Cl)cc1
