Task: Answer the multiple choice question.
Query: Which drug has a -26.313% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=[N+]([O-])c1cc(-c2nnc(Nc3ccccc3)c3ccccc23)ccc1N1CCOCC1
b) Cn1c(=O)c2c(nc(SCc3nc(N)nc(N4CCCCC4)n3)n2C)n(C)c1=O
c) CCc1ccc2[nH]c(C(=O)Nc3ccc4c(c3)OCO4)cc2c1
d) O=[N+]([O-])c1ccccc1SNc1ccccn1
Answer: a. O=[N+]([O-])c1cc(-c2nnc(Nc3ccccc3)c3ccccc23)ccc1N1CCOCC1
