Consider ten identical sources of sound all giving the same frequency but having phase angles which are random. If the average intensity of each source is \[{{I}_{0}}\], the average of resultant intensity I due to all these ten sources will be [MP PMT 1990]

• A.            \[I=100\,{{I}_{0}}\]            
• B.            \[I=10\,{{I}_{0}}\]
• C.            \[I={{I}_{0}}\]                      
• D.            \[I=\sqrt{10}\,{{I}_{0}}\]
