Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.691\% 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, d, or e without using any additional words.
Options:
a.) C=CCSc1n[nH]c(-c2ccccc2)n1
b.) CCC(C)(C(=O)NC1CCCC1)N(C(=O)CC1NC(=O)NC1=O)c1c(C)n(C)n(-c2ccccc2)c1=O
c.) O=C(CSc1nnc(NC(=O)c2c(F)cccc2Cl)s1)Nc1ccccc1F
d.) O=C(N/C(=C\c1ccco1)C(=O)N1CCOCC1)c1ccc([N+](=O)[O-])cc1
e.) O=C1N/C(=N/O)S/C1=C\c1ccccc1-n1cccn1
Answer: a. C=CCSc1n[nH]c(-c2ccccc2)n1
