Task: Answer the multiple choice question.
Query: Which drug exhibits a -24.911\% 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.) O=C(CCN1CCN(C(c2ccccc2)c2ccccc2)CC1)N/N=C/c1ccc(O)cc1
b.) CC1CCc2nc(N)c(C#N)c(-c3ccncc3)c2C1
c.) COc1ccc(S(=O)(=O)Cc2ccc(C(=O)NCc3cccs3)o2)cc1
d.) O=C(Nc1cccc(S(=O)(=O)N2CCOCC2)c1)c1ccc(Cl)c([N+](=O)[O-])c1
Answer: a. O=C(CCN1CCN(C(c2ccccc2)c2ccccc2)CC1)N/N=C/c1ccc(O)cc1
