Consider the following statements :
`S_(1) : - 8 = 2ixx 4i = sqrt((-4)) xx sqrt((-16)) " " S_(2) : sqrt((-4) )xx sqrt((-16)) = sqrt( (-4) xx (-16))`
`S_(3) : sqrt((-4) xx (16) )= sqrt( -64)" " S_(4) : sqrt(64)= 8`
Of these statements, the incorrect one is :

Options

A. `S_(1)` only
B. `S_(2) ` only
C. `S_(3)` only
D. None of these

Answer
