To simplify the expression \((16 - 12)^2 + \frac{5(8 + 2^2)}{5^3} - (1 + 4)^2\):

  1. Calculate \((16 - 12)^2\): \[ (16 - 12) = 4 \quad \text{so} \quad (4)^2 = 16 \]

  2. Calculate \(2^2\): \[ 2^2 = 4 \]

  3. Then calculate \(8 + 2^2\): \[ 8 + 4 = 12 \]

  4. Now calculate \(5(8 + 2^2)\): \[ 5(12) = 60 \]

  5. Calculate \(5^3\): \[ 5^3 = 125 \]

  6. Now, calculate \(\frac{5(8 + 2^2)}{5^3}\): \[ \frac{60}{125} = \frac{12}{25} \]

  7. Calculate \((1 + 4)^2\): \[ (5)^2 = 25 \]

  8. Putting it all together: \[ 16 + \frac{12}{25} - 25 \]

    To simplify \(16 - 25\): \[ 16 - 25 = -9 \]

    Now combine with \(\frac{12}{25}\): \[ -9 + \frac{12}{25} = -\frac{225}{25} + \frac{12}{25} = -\frac{213}{25} \]

The entire expression simplifies to \[ -\frac{213}{25} \]

Now assessing the list of given responses for the numerator (assuming integers):

  • 100
  • \(42 + 60\) (which evaluates to \(102\))
  • 54
  • 76

None of these seem to match \(-213\) or any equivalent form.

Given that we're examining for simplification in the numerator:

  • From parts of the expression computed: \(16\) and \(-25\),
  • There isn't a clear match.

Therefore, it seems none of the given responses match the simplified values obtained from the expression as examined here.

If this is potentially a flaw in interpreting the task or if any alternative simplification directly points to a choice made earlier, please clarify. But with straightforward calculations, results deviate from presented options.
