Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.507\% 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. COc1ccc(/C=N/NC(=O)Cn2cnc3ccccc3c2=O)cc1
b. O=C(Nc1nnc(C2CC2)s1)C1Cc2ccccc2CN1S(=O)(=O)c1ccccc1F
c. COc1ccc(CC(C)N2CCN(Cc3ccccc3)CC2)cc1OC
d. CCCCCn1c(=S)[nH]c2cc(C(=O)N3CCN(C(=O)OCC)CC3)ccc2c1=O
