Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.782\% 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 additional words.
Options:
a. C=CCOc1ccc2nc(NC(=O)OC)[nH]c2c1
b. O=C(NC1CCCCCC1)c1ccc(CS(=O)(=O)Cc2ccc(F)cc2)o1
c. Cc1cc([N+](=O)[O-])cc2c1-c1ncccc1C2=Nc1ccccc1
d. COCCNC(=O)C(c1ccc(F)cc1)N(Cc1ccco1)C(=O)CCC(=O)Nc1ccccn1
Answer: a. C=CCOc1ccc2nc(NC(=O)OC)[nH]c2c1
