Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.155\% 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 additional words.
Options:
a O=C(Cc1ccc(Br)cc1)Nc1cccc(Cl)c1
b Cc1c(NS(=O)(=O)c2ccccc2)cc(Cl)c(O)c1C
c Cc1ccc(C2N(c3cccc(Cl)c3)C(=O)N3CCCN23)cc1
d COC(=O)c1ccc(CC(=O)c2c(C)cc(O)cc2O)o1
Answer: d. COC(=O)c1ccc(CC(=O)c2c(C)cc(O)cc2O)o1
