Task: Answer the multiple choice question.
Question: Which compound has a 1.415\% 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, or d without using any additional words.
Options:
a COc1cc(OC)cc(-c2c(-c3cccs3)c3cc(-c4ccc5[nH]ccc5c4)ccc3n2C)c1
b CCN(CC)c1ccc(C2CC(=O)Nc3cc(OC)c(OC)cc32)cc1
c N#C/C(=C(/O)CCl)c1nc2ccccc2[nH]1
d O=C(O)CSc1c[nH]c2ccccc12
Answer: c. N#C/C(=C(/O)CCl)c1nc2ccccc2[nH]1
