Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.303\% 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(CC1SC(=Nc2ccc(OC(F)F)cc2)N(CCC2=CCCCC2)C1=O)Nc1ccccc1F
b.) CCOC(=O)c1c(CN2CCOCC2)n(-c2ccccc2)c2cc(Br)c(O)c(CN(C)C)c12
c.) N#Cc1cnc(Nc2nc3ccccc3o2)nc1-c1ccccc1
d.) Cn1c(O)c(C(=Nc2ccccc2)SCc2ccc(Cl)cc2)c(=O)n(C)c1=O
Answer: b. CCOC(=O)c1c(CN2CCOCC2)n(-c2ccccc2)c2cc(Br)c(O)c(CN(C)C)c12
