Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

[tex]5+7(8r-2)[/tex]

Using distributive property, the above expression can be written as

[tex]5+7(8r)+7(-2)[/tex]                [tex][\because a(b+c)=ab+ac][/tex]

[tex]5+56r-14[/tex]

On combining like terms we get,

[tex]56r+(5-14)[/tex]

[tex]56r+(-9)[/tex]

[tex]56r-9[/tex]

The expression 56r-9 is equivalent to the given expression.

Therefore the correct option is D.
