Task: Answer the multiple-choice question.
Query: Which compound has a 13.618\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCOc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(CCCO)nn21
(b) COC(=O)c1cc(S(=O)(=O)Nc2cccc(OC)c2)cn1C
(c) COC(=O)C1=C(C(=O)OC)[C@@H]2N(C)c3ccccc3[C@@]23C[C@@H](C(=O)OC)N=C3N1
(d) CCOc1ccccc1NC(=O)CCCCCN1C(=O)[C@@H]2Cc3ccccc3CN2C1=O
Answer: a. CCOc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(CCCO)nn21
