When a number \(N\) is divided by \(a\), the number can be written as;
\(N = aQ + r\)
where,
\(Q\) = quotient
\(r\) = remainder
So, \(x = yz + r\)
i.e. \(r = x - yz\)
Hence, option D

There's a nice rule that say, "If N divided by D equals Q with remainder R, then N = DQ + R"
For example, since 17 divided by 5 equals 3 with remainder 2, then we can write 17 = (5)(3) + 2
Here we're told that when x is divided by y, the quotient is z with remainder r
So, we can write: x = yz + r
Now subtract yz from both sides to get: x - yz = r
Answer: D
