we will check each options
option-A:
The modulus represents the distance between the complex number and the origin
we know that modulus is a kind of distance
For example: if we have to find modulus of x+iy
we get
that is also distance between (0,0) and (x,y)
so, this is TRUE
option-B:
It is also similar to Pythagoras theorem
so, this is also TRUE
option-C:
we got modulus formula
we know that value of sqrt can never be negative because it will always result in positive value
so, this is FALSE
option-D:
It is also similar to absolute value
so, this is TRUE
