Task: Answer the multiple choice question.
Question: Which compound exhibits a -38.921% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=Cc1cn(Cc2ccc([N+](=O)[O-])cc2)c2ccccc12
b) Cc1ccsc1/C=N/NC(=O)c1sccc1C
c) Cc1ccc(NC(=O)CN2C(=O)NC3(CCc4ccccc43)C2=O)cc1S(=O)(=O)N1CCCCC1
d) O=C(NNC(=O)C1CCCO1)c1ccc([N+](=O)[O-])cc1
Answer: a. O=Cc1cn(Cc2ccc([N+](=O)[O-])cc2)c2ccccc12
