Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.723\% 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 O=C1CSC(=Nc2ccc(F)cc2)N1
b Cn1c(SCC(=O)NNC(=O)c2ccccc2Br)nnc1C(F)(F)F
c CCC1=C(OC(=O)c2ccccc2)C(C)(C)C(c2ccccc2)OC1=O
d Cc1ccccc1Nc1c(-c2ccc(N3CCOCC3)cc2)nc2cnccn12
Answer: b. Cn1c(SCC(=O)NNC(=O)c2ccccc2Br)nnc1C(F)(F)F
