Task: Answer the MCQ question.
Query: Which drug exhibits a 3.852\% 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. O=C(NCCc1cccs1)C1CC(c2cccc([N+](=O)[O-])c2)=NO1
b. CCOc1ccccc1C(=O)NCC(=O)Nc1ccc2c(c1)OCO2
c. COc1ccc(C(=O)NCCC(=O)NCc2cc(=O)n(C)c(=O)n2C)cc1
d. O=C(Nc1ccc(-c2nc3ccccc3c(=O)o2)cc1)c1ccco1
Answer: d. O=C(Nc1ccc(-c2nc3ccccc3c(=O)o2)cc1)c1ccco1
