Explanation: Wired: M\(\to\)F\(\to\)B\(\to\)K\(\to\)J\(\to\)M. Radio (two-way): F\(\leftrightarrow\)S, S\(\leftrightarrow\)J, B\(\leftrightarrow\)A. A minimum of two intermediaries means a path of 3 steps (Start \(\to\) Int 1 \(\to\) Int 2 \(\to\) End). A: Mokter to Anis. M\(\to\)F\(\leftrightarrow\)S\(\leftrightarrow\)J\(\to\)M (4 steps: M\(\to\)J). M\(\to\)F\(\to\)B\(\leftrightarrow\)A (3 steps: M\(\to\)B\(\leftrightarrow\)A (2 Int)). M\(\to\)F\(\to\)B (1 Int). M\(\to\)F\(\to\)B\(\to\)K\(\to\)J\(\to\)M. M\(\to\)F\(\to\)B \(\leftrightarrow\) A. The path is M \(\to\) F \(\to\) B \(\leftrightarrow\) A. M to A: Intermediaries are F and B. (M \(\to\) F \(\to\) B \(\to\) A). This requires 2 intermediaries. F and B. B: F to J. F\(\leftrightarrow\)S\(\leftrightarrow\)J (1 Int). C: S to B. S\(\leftrightarrow\)F\(\to\)B (1 Int). D: B to A. B\(\leftrightarrow\)A (0 Int). E: K to S. K\(\to\)J\(\leftrightarrow\)S (1 Int). The pair requiring a minimum of two intermediaries is Mokter to Anis (M \(\to\) F \(\to\) B \(\leftrightarrow\) A).
