Fluorine will always form an anion. That is because at its basic form, it is electronegative, which means that it attracts electrons who give it a negative charge. This is why it will form an anion.
Answer:
The correct answer is option E.
Explanation:

Mass of ferric oxide decomposed = 57.0 g
Moles of ferric oxide decomposed = 
According to reaction, 2 moles ferric oxide on combustion gives 824.2 kJ of heat.
Then heat given by on decomposition of 0.35625 mol of ferric oxide will be:

So, on decomposition of 57.0 grams of ferric oxide 147 kilo Joules of heat was released.
