Answer:
C) Fluorine has the strongest tendency to attract electrons.
Explanation:
Electronegativity is the tendency of the atom in a covalent bond to attract the shared pair of electron towards itself.
Down the group, size increases which means that the nucleus become far from the valence electrons and thus decreased electronegativity as there will be less tendency to attract the shared electrons.
Fluorine and iodine are in the same group and thus fluorine has higher tendency to attract electrons and thus has the highest electronegativity.

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers, than finally after death of an organism, to decomposers
C + 1/2O2 => CO
Monoxide is forming if there is no enough oxigen to combine with
