Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 11.604\% 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 other words.
Options:
a: CCNC(=O)[C@H]1O[C@@H](n2cnc3c(N)ncnc32)[C@H](O)[C@@H]1O
b: CC(CCc1ccccc1)NC(=O)CN(C)Cc1ccccc1F
c: CCOC(=O)N1C=CC=C[C@@H]2[C@@H](N3C(=O)c4ccccc4C3=O)C(=O)N21
d: COCCNC(=O)CSc1nnc(-c2ccccc2)c(-c2ccccc2)n1
e: CN1CCc2cc3c(c4c2C1Cc1ccccc1-4)OCO3
Answer: a. CCNC(=O)[C@H]1O[C@@H](n2cnc3c(N)ncnc32)[C@H](O)[C@@H]1O
