**True or False?**

\(\quad\) If \(\color{red}{a},\color{blue}{b},\) and \(\color{green}{c}\) are non-zero reals and \(\color{red}{a}>\color{blue}{b},\) then \( \color{red}{a}^{\color{green}{c}} > \color{blue}{b}^{\color{green}{c}}. \)

Given three numbers such that \( 0 < a < b < c < 1\), define

\[ A = a^{a}b^{b}c^{c}, \quad B = a^{a}b^{c}c^{b} , \quad C = a^{b}b^{c}c^{a}. \]

How do the values of \(A, B, C \) compare to each other?
