Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -4.925\% 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=[N+]([O-])c1ccc(Cl)c(/C=N/n2c(C3CCCCC3)n[nH]c2=S)c1
b CCC(=O)Nc1nc2c(OC)ccc(C)c2s1
c CC(Oc1ccc(Br)cc1)c1nc2c3ccccc3nc(=S)n2[nH]1
d Cc1ccc(S(=O)(=O)NC(Cc2ccccc2)C(=O)O)cc1
Answer: a. O=[N+]([O-])c1ccc(Cl)c(/C=N/n2c(C3CCCCC3)n[nH]c2=S)c1
