Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -5.923\% 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 CCOC(=O)c1ccc2c(c1)nc(SC/C(O)=C(\C#N)c1nc3ccccc3[nH]1)n2CC
b CCOC(=O)/C(=N\Nc1ccccc1Cl)N1CCN(C)CC1
c Cc1ccc(N(CC(=O)N2CCN(c3ccc(F)cc3)CC2)S(=O)(=O)c2c(C)noc2C)cc1
d Cn1c(=O)[nH]c(=O)c2c1nc(Br)n2CCCSc1nc2ccccc2o1
Answer: b. CCOC(=O)/C(=N\Nc1ccccc1Cl)N1CCN(C)CC1
