Task: Answer the multiple choice question.
Query: Which drug has a -1.524\% 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 additional words.
Options:
a) Cc1ccc(Nc2c([N+](=O)[O-])ccc3nonc23)cc1C
b) O=C(c1cccs1)N(Cc1ccccn1)Cc1ccco1
c) COc1ccc(C=O)cc1COc1ccc([N+](=O)[O-])c(C)c1
d) COc1cc2c(cc1OC)-c1nnc(-c3cccs3)n1C(C)(C)C2
Answer: b. O=C(c1cccs1)N(Cc1ccccn1)Cc1ccco1
