Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.635\% 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. CC(=O)N1CCN(C(=O)C2(NC(=O)Nc3ccc(C)cc3)CCCCC2)CC1
b. COC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccc(F)cc1
c. CCOc1ccc(-c2c(C(=O)N/N=C/c3ccc(C)s3)nnn2-c2nonc2N)cc1
d. COc1ccc(OC)c(NC(=O)NCCCCc2ccccc2)c1
Answer: b. COC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccc(F)cc1
