(B) Given that the metal oxide contains $20\%$ oxygen by weight.Therefore,the percentage of metal by weight is $100\% - 20\% = 80\%$.The equivalent weight of an element is calculated using the formula: $	ext{Equivalent weight of metal} = \frac{	ext{Weight of metal}}{	ext{Weight of oxygen}} 	imes 	ext{Equivalent weight of oxygen}$.The equivalent weight of oxygen is $8$.Substituting the values: $	ext{Equivalent weight of metal} = \frac{80}{20} 	imes 8 = 4 	imes 8 = 32$.
