Task: Answer the multiple choice question.
Query: Which drug exhibits a -49.056\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(OCCCN=C1NS(=O)(=O)c2ccccc21)c1ccccc1F
(b) COCCN(C(=O)COC(=O)c1c(-c2ccccc2)noc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
(c) CN(C)Cc1ccccc1C(O)(c1ccccc1)c1ccccc1
Answer: b. COCCN(C(=O)COC(=O)c1c(-c2ccccc2)noc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
