Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.987\% 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. CCOC(=O)Nc1ccc2c(c1)N(C(=O)CN1CCN(C)CC1)c1ccccc1CC2.Cl
b. CCOc1cnc(-c2c(-c3ccccc3Cl)noc2C)o1
c. O=C(CN1C(=O)C2CCCCC2C1=O)OCn1nnc2ccccc2c1=O
d. Nc1nc(SCC(=O)c2ccc([N+](=O)[O-])cc2)n[nH]1
e. Cc1ccc(/C=N/NC(=O)c2nnn(-c3nonc3N)c2C)o1
Answer: b. CCOc1cnc(-c2c(-c3ccccc3Cl)noc2C)o1
