Task: Answer the multiple choice question.
Question: Which drug has a 17.663\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccccc1/C=C/C(=O)NC(=S)NCC1CCCO1
(b) COC(=O)c1ccc(NC(=O)CCN2C(=O)C3CC=CCC3C2=O)cc1
(c) O=C(O)CC/C(=N\NC(=O)c1ccncc1)c1ccccc1
Answer: c. O=C(O)CC/C(=N\NC(=O)c1ccncc1)c1ccccc1
