Answer:

Option A.

Step-by-step explanation:

The given expression is

[tex]83 g-1.8 g[/tex]

We need to find the difference round to the less precise measurement.

Taking out the common factor.

[tex](83-1.80)g[/tex]

[tex]81.2g[/tex]

Precise measurement of given expression is 81.2g.

A measurement with more decimal places is more precise and vice versa.

Now, approx the answer to the the nearest whole measure.

[tex]81.2g\approx 81g[/tex]

The less precise measurement of given expression is 81g.

Therefore, the correct option is A.
