Task: Answer the multiple choice question.
Query: Which drug has a 15.371% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a C=CCNC(=O)C12CCC(C)(C(=O)C1Br)C2(C)C
b O=C(CN1C(=O)c2ccccc2S1(=O)=O)NCCSCc1cccc(Cl)c1
Answer: a. C=CCNC(=O)C12CCC(C)(C(=O)C1Br)C2(C)C
