Task: Answer the multiple-choice question.
Query: Which drug has a 13.521\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) C=CCn1c(NCc2ccccc2O)nc2ccccc21
b) O=C(OCC(=O)N1CCCc2ccccc21)c1cncc(Br)c1
c) C/C=C/C=C/C(=O)Nc1cccc(C2=NOC3(C2)C[C@H](C(N)=O)N(C(=O)CC(c2ccccc2)c2ccccc2)C3)c1
Answer: a. C=CCn1c(NCc2ccccc2O)nc2ccccc21
