Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.400\% 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(Nc1ccc(S(=O)(=O)NCc2ccco2)cc1)c1ccc2ccccc2n1
b O=C1/C(=C/Nc2ccc3c(c2)OCO3)CCc2ccccc21
c N#Cc1cn(CCOc2ccc(F)cc2)c2ccccc12
d Cc1ccc(C(=O)NCC(=O)N/N=C/c2sccc2C)cc1[N+](=O)[O-]
Answer: a. O=C(Nc1ccc(S(=O)(=O)NCc2ccco2)cc1)c1ccc2ccccc2n1
