Solution

The correct options are
A
Fluorine is the most electronegative element

B
Electronegativity is directly proportional to nuclear charge

D
Electropositive elements tend to let go their valence electrons

Fluorine is the smallest halogen thus being the smallest in size to attract electrons which makes it the most electronegative element in the periodic table.

Elements that have a strong tendency to release the valence electrons to attain noble gas configuration are called electropositive elements.

Nuclear charge is directly proportional to electronegativity whereas atomic radius is inversely proportional to electronegativity.
