Which of the following is a possible rational root of the polynomial P(x) = 2x³ - 5x² + x + 6?

✓ Correct Answer: Option B

According to the Rational Root Theorem, possible rational roots p/q have p as a factor of 6 and q as a factor of 2. Factors of 6: ±1, ±2, ±3, ±6. Factors of 2: ±1, ±2. The fraction 3/2 is a possible p/q.
