Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.284\% 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 other words.
Options:
a. CN(C)Cc1c(O)ccc2c1O/C(=C\C=C\c1ccccc1)C2=O
b. Cc1ccc(N2C(=O)[C@@H]3[C@@H]4O[C@@H]([C@H]5ON=C(c6ccccc6Cl)[C@H]54)[C@@H]3C2=O)cc1
c. CC1(C(=O)Nc2ccc3c(c2)OCCO3)CC1(Cl)Cl
d. CC(C)OC(=O)CC1C(=O)NCCN1C(=S)NC(=O)c1ccccc1Cl
Answer: b. Cc1ccc(N2C(=O)[C@@H]3[C@@H]4O[C@@H]([C@H]5ON=C(c6ccccc6Cl)[C@H]54)[C@@H]3C2=O)cc1
