Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 6.738\% 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 additional words.
Options:
a.) CC1=Nn2c(nnc2-c2ccccc2)SC1
b.) O=C1N/C(=N\c2ccccn2)SC1Cc1ccc(Cl)cc1
c.) O=C(COC(=O)/C=C/c1cccc([N+](=O)[O-])c1)NCc1ccco1
d.) Cc1ccc(S(=O)(=O)N2CCOCC2)cc1C(=O)NC1CCCCCC1
Answer: a. CC1=Nn2c(nnc2-c2ccccc2)SC1
