Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.102\% 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, d, or e without using any other words.
Options:
a. O=C(CN1CCN(S(=O)(=O)/C=C/c2ccccc2)CC1)NCC(F)(F)F
b. COc1ccc(Br)cc1CN(C)CC(=O)Nc1c(Cl)cccc1Cl
c. Cn1cccc1C(=O)NC(=O)COC(=O)Cc1coc2ccc3ccccc3c12
d. Cc1ccc(C(=O)NC2CCN(C(=O)NCc3ccccc3)CC2)cc1
e. O=C1CCCc2c1cc(C(=O)O)c(=O)n2-c1ccccc1
Answer: b. COc1ccc(Br)cc1CN(C)CC(=O)Nc1c(Cl)cccc1Cl
