Task: Answer the multiple choice question.
Query: Which drug has a 18.517\% 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] Nc1c(-c2ccc(Cl)cc2)cnc2c(-c3ccccc3)cnn12
[b] CN(C)c1ccc(/C=N/NC(=O)c2ccc(Cn3cc(Br)cn3)o2)cc1
[c] Cc1nc(Nc2nc3ccccc3o2)nc2c1CCC2
[d] O=C(COC(=O)/C=C/c1ccco1)NCc1ccco1
Answer: a. Nc1c(-c2ccc(Cl)cc2)cnc2c(-c3ccccc3)cnn12
