Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.888\% 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, or c without using any additional words.
Options:
a: CCOC(=O)Cn1c(=O)c(-c2ccccc2NC)nc2ccccc21
b: Cc1nc2ccccc2c(=O)n1/N=C/C=C/c1ccccc1
c: Cc1cc(C)c(NC(=O)CNC(=O)COC(=O)CN2C(=O)NC3(CCCC3)C2=O)c(C)c1
Answer: a. CCOC(=O)Cn1c(=O)c(-c2ccccc2NC)nc2ccccc21
