Task: Answer the multiple choice question.
Question: Which drug has a -3.252\% 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) O=C(/C=C/c1ccco1)c1ccc(O)cc1
(b) COc1ccc2ccc(OCC(=O)N3c4ccccc4NC(=O)CC3C)cc2c1
(c) N#Cc1cc(-c2ccccc2)cnc1Cl
(d) CCCOC(=O)c1ccc(Oc2coc3c(CN(CC)CC)c(O)ccc3c2=O)cc1
Answer: a. O=C(/C=C/c1ccco1)c1ccc(O)cc1
