Task: Answer the multiple choice question.
Question: Which compound has a 12.796\% 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 additional words.
Options:
(a) C=CCn1c(CSc2ccc(C)cc2)n[nH]c1=S
(b) O=C(O)CN1C(=O)S/C(=C\c2cccnc2)C1=O
(c) CCN1CCN(CCCNC(=O)CS(=O)(=O)Cc2nc(-c3ccccc3C)oc2C)CC1
(d) O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCc1cccnc1
Answer: b. O=C(O)CN1C(=O)S/C(=C\c2cccnc2)C1=O
