To simplify the expression \(17xyz + 11xyz - 21xyz - 5xyz\), we can start by combining like terms:

  1. Combine all the coefficients of \(xyz\): \[ 17 + 11 - 21 - 5 \]

  2. Calculate step-by-step:

    • \(17 + 11 = 28\)
    • \(28 - 21 = 7\)
    • \(7 - 5 = 2\)

So, the simplified expression is: \[ 2xyz \]

Thus, the correct response is: 2xyz
