a,\;b,\;c,\;d\;\mathrm{and}\;p

are different real numbers such that

\left( {{a^2} + {b^2} + {c^2}} \right)\;{p^2} - 2\left( {ab + bc + cd} \right)\;\;p + \left( {{b^2} + {c^2} + {d^2}} \right) \le 0,\mathrm{then}\;a,\;b,\;c,\;d

are in

View answer and explanation

Correct option: B

Option B (GP) is correct because the given condition implies that
