Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 17.601\% 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: Cn1c(=O)[nH]c(=O)c2c1nc(N1CCOCC1)n2CCc1ccccc1
b: O=c1oc(-c2ccccc2)nc2c1cnn2-c1ccccc1
c: O=C(O)CC(O)C(=O)O
d: O=C(Nc1cc(N2CCOCC2)ncn1)c1ccccc1
e: COc1ccc(OC)c(C(=O)N(C)C2CCCN(Cc3ccccc3F)C2)c1
Answer: c. O=C(O)CC(O)C(=O)O
