Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.004\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCN1CCN(C(=S)Nc2sc(C)c(-c3ccccc3)c2C(=O)OC)CC1
b: C=Cc1ccc(COC(=O)c2cn(CC)c3nc(C)ccc3c2=O)cc1
c: O=C1CCCCCN1C(=O)c1ccc(C(=O)N2CCCCCC2=O)cc1
d: Cc1ccc(S(=O)(=O)N2CCC(C(N)=O)CC2)c(C)c1C
e: CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(NC(=O)c2nn(C)c(=O)c3ccccc23)c1
Answer: b. C=Cc1ccc(COC(=O)c2cn(CC)c3nc(C)ccc3c2=O)cc1
