Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -6.374% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=c1c2ccccc2nc(SCc2cc([N+](=O)[O-])cc3c2OCOC3)n1-c1ccccc1
b. COC(CNC(=O)c1ccc(Cn2c(=S)[nH]c3cc4c(cc3c2=O)OCO4)cc1)OC
c. CCOCCCNC(=O)CN1N=C(c2ccc(C)cc2)CCC1=O
d. Cc1ccc(NCC(=O)N=Nc2c(O)n(C)c3ccccc23)cc1
e. Cc1ccc(-c2cc[n+](Cc3ccccc3)cc2)cc1.[Cl-]
Answer: a. O=c1c2ccccc2nc(SCc2cc([N+](=O)[O-])cc3c2OCOC3)n1-c1ccccc1
