Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.958\% human ether-à-go-go related gene (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: CCN(C(=O)CO/N=C/c1ccc(OC)cc1OC)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
b: CCn1ncc(-c2csc(N)n2)c1C
c: O=C(NCc1ccccn1)c1n[nH]c(=O)c2ccccc12
d: Cc1cc(C)c(Cn2c(C(=O)O)c(C=O)c3ccccc32)c(C)c1
e: C=CCn1c(Sc2ccc(S(=O)(=O)NCCCN(C)C)cc2[N+](=O)[O-])nnc1C1CCCCC1
Answer: b. CCn1ncc(-c2csc(N)n2)c1C
