Task: Answer the multiple choice question.
Query: Which drug has a -3.482\% 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 or b without using any additional words.
Options:
(a) CCCn1c(C)cc(-c2csc(NC(=O)CCc3nc4ccccc4c(=O)[nH]3)n2)c1C
(b) O=C(NCc1ccccc1)C1=C[C@@H](c2ccccc2)C[C@@H](OCCCCO)O1
Answer: b. O=C(NCc1ccccc1)C1=C[C@@H](c2ccccc2)C[C@@H](OCCCCO)O1
