An AM wave is expressed as \( \mathrm{e}=10(1+0.6 \cos 2000 \pi \mathrm{t}) \cos \) \( 2 \times 10^{8} \pi \mathrm{t} \) volts, the minimum and maximum value of modulated carrier wave are respectively.
(a) \( 10 \mathrm{~V} \) and \( 20 \mathrm{~V} \)
(b) \( 4 \mathrm{~V} \) and \( 8 \mathrm{~V} \)
(c) \( 16 \mathrm{~V} \) and \( 4 \mathrm{~V} \)
(d) \( 8 \mathrm{~V} \) and \( 20 \mathrm{~V} \)
