Task: Answer the multiple-choice question.
Question: Which drug exhibits a -27.326\% 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, or d without using any other words.
Options:
a CCOc1ccc2nc(NCCNC(=O)C(C)C)c(C)cc2c1
b O=C(CSc1nccn1-c1ccc(F)cc1)Nc1ccc2c(c1)OCO2
c CCCNC(=O)c1cccc(C(F)(F)F)c1
d COc1cc2c(cc1OC)C(C(=O)NC(C)c1ccccc1)CC(=O)N2
Answer: a. CCOc1ccc2nc(NCCNC(=O)C(C)C)c(C)cc2c1
