The group 17 elements of the periodic table have 7 valence electrons and are highly reactive, with low melting and boiling points. The halogens - including fluorine, chlorine and bromine - have a common tendency to form salts, but they are all of a toxic nature.

The correct answer is e. 3.57×10³
Al³+(aq) + 3e→AL(s)
4.00g of AL=4g/26.98 g/mol= 0.1483 mol
t=znF/1 where t is time in seceonds.
Z= valency number of ions of the substance or electrons which are transferred per ion
F= Faraday's constant
I = electric current in'A'CA C/s
t=(3×0.1483 mol ×96485 C/mol) /12(C15)
t=3577 second = 3.5 ×10³s
