Task: Answer the multiple choice question.
Query: Which compound has a 4.217\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCC(C)(C(=O)NC1CCCC1)N(C(=O)c1cnccn1)c1c(C)n(C)n(-c2ccccc2)c1=O
b: CCN(CC)S(=O)(=O)c1ccc2nc(COC(=O)c3n[nH]c4ccccc34)[nH]c2c1
c: CCOc1c(OC(C)=O)ccc(/C=C/c2ccc3cccc(OC(C)=O)c3n2)c1[N+](=O)[O-]
d: O=C(N/N=C/c1cc(Br)c(Br)o1)c1cc2ccccc2o1
Answer: a. CCC(C)(C(=O)NC1CCCC1)N(C(=O)c1cnccn1)c1c(C)n(C)n(-c2ccccc2)c1=O
