Task: Answer the multiple choice question.
Query: Which drug has a -4.357\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(c1cccs1)n1nc(-c2ccccc2)nc1NCc1ccco1
b.) Cc1c(C(=O)N(C)C)sc2nc(-c3ccccn3)[nH]c(=O)c12
c.) CS(=O)(=O)c1ccc(C(=O)OCC(=O)NC(=O)C2CCCCC2)cc1[N+](=O)[O-]
Answer: a. O=C(c1cccs1)n1nc(-c2ccccc2)nc1NCc1ccco1
