Answer 1

The Correct Option is B

To find the value of 28 mod 3, we need to determine the remainder when 28 is divided by 3.

First, perform the division:

$\frac{28}{3}$

which equals 9 with a remainder of 1, because:

$9^1\cdot 3+1=28$

The remainder r when dividing 28 by 3 is 1. Therefore:

$28mod3=1$

So, the value of 28 mod 3 is 1.
