Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.512\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C1CN(C(=O)/C=C/c2ccc(Cl)cc2Cl)CCN1
b: CCCc1cc(=O)[nH]c(SCC(=O)NC)n1
c: CCCN(CC(=O)Nc1cccc(S(N)(=O)=O)c1)CC(=O)Nc1ccc(F)c(F)c1F
d: Cc1ccc2oc(C(=O)NCc3ccccc3)cc(=O)c2c1
e: Cc1ccc(NC(=O)C2CCCN(S(=O)(=O)c3ccc4[nH]c(=O)ccc4c3)C2)cc1C
Answer: b. CCCc1cc(=O)[nH]c(SCC(=O)NC)n1
