Problem statement: Answer the multiple-choice question.
Query: Which compound has a 8.938\% 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 other words.
Options:
a: COc1ccc(C(=O)Oc2ccc(=O)n(-c3ccccc3)n2)cc1
b: CCOc1ccccc1NC(=O)CSc1c(C)n[nH]c1C
c: CCC(=O)Oc1ccc2c(c1)OC1(OC(C)=O)OC(C)CC1=C2C
d: CCOC(=O)c1c(C)[nH]c(C)c1C(=O)COC(=O)CCOc1ccccc1OC
e: O=[N+]([O-])c1ccc(N2CCOCC2)c2ccncc12
Answer: c. CCC(=O)Oc1ccc2c(c1)OC1(OC(C)=O)OC(C)CC1=C2C
