Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.322\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(NC(=S)Nc1ccccc1N1CCOCC1)c1ccccc1F
b Cc1cccc(NC(=O)COC(=O)c2cc3ccccc3oc2=O)c1
c Cl.OC(CN1C2=NCCN2c2ccccc21)c1ccccc1
