Task: Answer the multiple-choice question.
Query: Which drug has a 15.510\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a NNC(=S)Nc1ccc(S(=O)(=O)N2CCCCC2)cc1
b O=C(CNC(=O)c1ccccn1)N=Nc1c(O)[nH]c2ccccc12
c COc1ccc(CCNC(=O)CCc2nc3ccccc3[nH]2)cc1OC
Answer: b. O=C(CNC(=O)c1ccccn1)N=Nc1c(O)[nH]c2ccccc12
