Correct Answer: B
Solution :
Time period of communication satellite \[{{T}_{c}}=1\ \text{day}\] Time period of another satellite = \[{{T}_{s}}\] \[\frac{{{T}_{s}}}{{{T}_{c}}}={{\left( \frac{{{r}_{s}}}{{{r}_{c}}} \right)}^{3/2}}={{(4)}^{3/2}}\Rightarrow {{T}_{s}}={{T}_{c}}\times {{(4)}^{3/2}}=8\ \text{days}\text{.}\]
