Task: Answer the multiple choice question.
Query: Which compound has a 4.893\% 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: CCCCN1C(=O)/C(=C2/C=CC=CN2C)SC1=S
b: CC(=O)OCCc1[nH]c2ccccc2c1C
c: COc1ccc(S(=O)(=O)Nc2ccc(Nc3ccccc3)cc2)cc1
d: CN(C(=O)COC(=O)COc1ccc2c(c1)CCC2)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: a. CCCCN1C(=O)/C(=C2/C=CC=CN2C)SC1=S
