Task: Answer the multiple choice question.
Query: Which drug has a -0.527\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) C=CCn1c(SCC(=O)N2CCN(CCO)CC2)nc2sc3c(c2c1=O)CCC3
(b) Nc1c(C(=O)NCc2ccco2)c2nc3ccccc3nc2n1Cc1ccccc1
Answer: a. C=CCn1c(SCC(=O)N2CCN(CCO)CC2)nc2sc3c(c2c1=O)CCC3
