Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.075% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(Nc1ccccc1)NC1CCN(CCCN2C(=O)c3ccccc3C2=O)CC1
b O=C(O)COc1cccc(NC(=O)C2CCCO2)c1
c CCOc1ccccc1CNC(=O)c1ccc2c(c1)N(CC)CCS2
d COc1ccc2c(c1)c(=O)cc(-c1ccccc1)n2C
Answer: d. COc1ccc2c(c1)c(=O)cc(-c1ccccc1)n2C
