Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.846\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(Cc1ccc2c(c1)CCCC2)Nc1ccccc1Br
b Cn1c(NCc2cccc(Br)c2)nc2ccccc21
c Cc1ccc(S(=O)(=O)N(CC(=O)N2CCOCC2)CC(=O)N2CCOCC2)cc1
d N#Cc1cccc(NC(=O)CNc2cccc(S(=O)(=O)N3CCCCC3)c2)c1
e CCOC(=O)C1CCN(C(=O)C(=O)N2CCC(C(=O)OCC)CC2)CC1
Answer: b. Cn1c(NCc2cccc(Br)c2)nc2ccccc21
