Problem statement: Answer the multiple choice question.
Question: Which drug has a -6.717\% human ether-à-go-go related gene (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[C@H]1CN=C(N(C)C)N1CCCC1CCCC1
[b] COc1ccc(C(=O)OCC(=O)Nc2cc(C)on2)c(OC)c1OC
[c] COc1cccc(/C=N/NC(=O)c2cc(C34CC5CC(CC(C5)C3)C4)[nH]n2)c1
[d] C=CCN1C(=O)C(C)(C)Nc2ccccc21
Answer: a. C[C@H]1CN=C(N(C)C)N1CCCC1CCCC1
