Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.290\% 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 CCOC(=O)c1cc(C(=O)OCC)c(=O)[nH]c1C
b Cc1ccc(C(=O)Nc2c[nH]c(=O)[nH]c2=O)cc1
c Cc1ccc(C(=O)O/N=C(\N)c2ccc(C(F)(F)F)cn2)cc1
d CCn1cc(Br)c(C(=O)NN)n1
Answer: a. CCOC(=O)c1cc(C(=O)OCC)c(=O)[nH]c1C
