Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.683% 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 additional words.
Options:
a: CCn1c(-c2cc(Br)cc(OC)c2O)nc2cc(S(=O)(=O)N(C)C)ccc21
b: Cc1cccc(NC(=O)CNC(=O)CNC(=O)Cc2ccccc2)c1
c: Cc1ccc(-c2nc3ccccc3n2C)o1
d: CCOC(=O)CSC1=C(C#N)C(c2ccc(C)o2)CC(=O)N1
Answer: c. Cc1ccc(-c2nc3ccccc3n2C)o1
