Let α, β be the roots of ax2 + bx + c = 0; γ, δ be the roots of px2 + qx + r = 0 ;& D1 , D2 the respective discriminants of these equations. If α, β, γ, δ are in A.P. Then find the value of D1 : D2

• A. \(\frac{{{a^2}}}{{{p^2}}}\)
• B. \(\frac{{{a^2}}}{{{b^2}}}\)
• C. \(\frac{{{b^2}}}{{{q^2}}}\)
• D. \(\frac{{{c^2}}}{{{r^2}}}\)
