Task: Answer the multiple-choice question.
Question: Which compound has a 12.422\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)/C(C(N)=NCCCO)=C(\O)OCC
b. O=C(Cc1ccccc1)Nc1ccc(NC(=O)c2ccccc2)c(Cl)c1
c. COc1ccc(OC)c(C(C)NC(=O)c2ccc(Br)cc2)c1
d. Cc1ccc(S(=O)(=O)N(C)Cc2ccc(C(=O)N/N=C/c3ccc(OC(F)F)cc3OC(F)F)cc2)cc1
Answer: a. CCOC(=O)/C(C(N)=NCCCO)=C(\O)OCC
