For E₂ elimination of butane-1,4-diol(g)( labelled as A) to form 1,3-butadiene(g) and water (g)at constant volume and temperature, the total pressure at the beginning (t = 0 ) and at time t are p₀ and p₁, respectively. Initially, only diol is present with concentration  [A]₀, and t_1/3 is the time required for the partial pressure of A to reach 1/3^rd of its initial value. Then correct option(s) is(are)

 (Assume that all these gases behave as ideal gases)
