Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.963\% 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(NCCC1CCCCN1S(=O)(=O)c1cccs1)C(=O)Nc1ccc(F)cc1
b) O=C(Nc1ccccn1)c1ccco1
c) CS(=O)(=O)c1cnc(-c2ccccc2)nc1Sc1ccc(F)cc1
d) Cc1cccc(NC(=O)CSc2nnc(C)c(C)n2)c1
Answer: b. O=C(Nc1ccccn1)c1ccco1
