z is a positive integer and multiple of 2; p = 4^z, what is the remainder when p is divided by 10?	Choose the correct choice from the following choices:
A) 10  B) 6  C) 4  D) 0  E) It Cannot Be Determined
Given: z is an even Integer   The cyclicity of Unit Digit of 4 is 2 i.e. Unit digit of powers of 4 repeat after every two powers in the pattern {4, 6, 4, 6, 4, ....}   4^1=4   4^2=16   4^3=64   4^4=256   i.e. Every Even Power of 4 gives the Unit digit = 6 = Remainder   Answer: Option 6
<result>B</result>
