Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.863\% 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 other words.
Options:
a: CCOCCOC(=O)COc1ccc2c(-c3ccccc3)cc(=O)oc2c1
b: CC1CCCN(C(=O)CCc2ccccc2)C1
c: CCN1CCN(C(=S)Nc2ccc(Cl)c(Cl)c2)CC1
d: COc1cc(C(=O)NCCC(=O)N2CCCCC2)cc(OC)c1OC
Answer: a. CCOCCOC(=O)COc1ccc2c(-c3ccccc3)cc(=O)oc2c1
