Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.647\% 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) COc1ccc(OC)c(NC(=O)c2cccc(S(=O)(=O)N(Cc3ccccc3)c3ccccc3OC)c2)c1
(b) O=C(CCC1N=C2c3ccccc3N=C(SCc3ccc(Cl)cc3)N2C1=O)NCc1ccco1
(c) Cl.O=C(NCCN1CCCC1)c1ccc(Cl)cc1
(d) CCCOC(=O)c1cc2ccccc2oc1=O
Answer: d. CCCOC(=O)c1cc2ccccc2oc1=O
