Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.204\% 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 additional words.
Options:
a Cc1c(N=C2NN=C(c3c[nH]c4ccccc34)CS2)c(=O)n(-c2ccccc2)n1C
b CN(C)/C=N/c1cc(=O)n(Cc2ccccc2)c(=O)n1C
c COCCCNC(=O)Cn1cnc2sc(C)c(S(=O)(=O)N3CCN(c4ccccc4OC)CC3)c2c1=O
d CCc1cc(C(=O)COc2ccc(F)cc2)c(O)cc1O
e Cc1cccc(NC2=NC(=S)N(CC#N)C23CCCCC3)c1
Answer: b. CN(C)/C=N/c1cc(=O)n(Cc2ccccc2)c(=O)n1C
