Task: Answer the multiple choice question.
Question: Which drug has a 4.325\% 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) O=C1c2ccccc2C(=O)N1CCc1nc(-c2ccncc2)no1
(b) Nc1c(Cl)ncnc1N1CCCC1
(c) CCO[C@@H]1OC(C(=O)NCc2ccccc2)=C[C@H](C(C)(C)C)[C@H]1CCCO
(d) O=C1c2cccc3cccc(c23)C(=O)N1c1ccccn1
Answer: a. O=C1c2ccccc2C(=O)N1CCc1nc(-c2ccncc2)no1
