Sure, let's solve the expression step by step.

The given expression is [tex]$(3 \times 22) \div 6 + [28 - (4)^2]$[/tex].

1. Start with the multiplication inside the parentheses:
[tex]\(3 \times 22 = 66\)[/tex].

2. Next, divide the result by 6:
[tex]\(\frac{66}{6} = 11.0\)[/tex].

3. Then, handle the exponentiation inside the brackets:
[tex]\(4^2 = 16\)[/tex].

4. Subtract this result from 28:
[tex]\(28 - 16 = 12\)[/tex].

5. Finally, add the results of the division and the subtraction:
[tex]\(11.0 + 12 = 23.0\)[/tex].

So, the simplified result of the expression is:
[tex]\[23.0.\][/tex]

Therefore, the best answer is:
A. 23
