Task: Answer the multiple choice question.
Question: Which compound has a -50.726% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1nc(NCCN2CCOCC2)nc(Nc2ccc([N+](=O)[O-])cc2)n1
(b) CCn1c(CSc2nnc(-c3ccc4c(c3)OCO4)o2)nc2cc(S(=O)(=O)N(C)C)ccc21
(c) Cc1ccc(O)c(/C=N/NC(=O)c2[nH]ncc2Br)c1
(d) C1COC(NC(C2CC2)C2CC2)=N1.O=C(O)/C=C/C(=O)O
Answer: a. COc1nc(NCCN2CCOCC2)nc(Nc2ccc([N+](=O)[O-])cc2)n1
