Task: Answer the multiple-choice question.
Question: Which drug has a 0.974\% 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 other words.
Options:
(a) O=C(C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCc2ccc(CO)cc2)O1)N1CCN(Cc2ccccc2)CC1
(b) Cc1ccc(N(C(=O)C2CCCC2)C2C=CS(=O)(=O)C2)cc1
(c) O=C(NCCc1ccccc1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
(d) COc1ccc(C(=O)NCc2ccc(Cl)cc2)cc1S(=O)(=O)N1CCCC1
Answer: a. O=C(C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCc2ccc(CO)cc2)O1)N1CCN(Cc2ccccc2)CC1
