(C) The slope of the anode characteristic is given by $1/r_p$,where $r_p$ is the plate resistance.Given $1/r_p = 0.02 	ext{ mA/V} = 0.02 	imes 10^{-3} 	ext{ A/V}$.Therefore,$r_p = 1 / (0.02 	imes 10^{-3}) = 50 	imes 10^3 \, \Omega = 50 \, 	ext{k}\Omega$.The slope of the mutual characteristic is the transconductance $g_m$.Given $g_m = 1 	ext{ mA/V} = 1 	imes 10^{-3} 	ext{ A/V}$.The amplification factor $\mu$ is defined as $\mu = r_p 	imes g_m$.Substituting the values: $\mu = (50 	imes 10^3 \, \Omega) 	imes (1 	imes 10^{-3} 	ext{ A/V}) = 50$.

The slope of the anode characteristic and the mutual characteristic of a triode are $0.02 \text{ mA/V}$ and $1 \text{ mA/V}$ respectively. The amplification factor of the valve is:
