Correct Answer: Option B

Explanation

For equal roots, \(b^{2} - 4ac = 0\)

From the equation, \(a = P, b = (P+1), c = P\)

\((P+1)^{2} - 4(P)(P) = P^{2} + 2P + 1 - 4P^{2} = 0\)

\(-3P^{2} + 2P + 1 = 0 \implies 3P^{2} - 2P - 1 = 0\)

\(3P^{2} - 3P + P - 1 = 0\)

\(3P(P - 1) + 1(P - 1) = 0\)

\(P = \text{1 or }\frac{-1}{3}\)
