For positive real number

a,b,c\;

which one of the following holds?

View answer and explanation

Correct option: A

{a^2} + {b^2} + {c^2} \ge bc + ca + ab

Option B (

\min \left( {p,q} \right) = \frac{1}{2}\left( {P + q - \left| {p - q} \right|} \right)

) is correct because it correctly defines the minimum of two numbers using the absolute value function.
