In a magnetic field of\[5\times {{10}^{-2}}T\], area of a coil changes from \[101\text{ }c{{m}^{2}}\]to \[100\text{ }c{{m}^{2}}\]without changing the resistance which is\[2\Omega \]. The amount of charge that flows during this period is:

A) \[2.5\times {{10}^{-6}}C\] 

B) \[2\times {{10}^{-6}}C\]

C) \[{{10}^{-6}}C\]                     

D) \[8\times {{10}^{-6}}C\]
