A
Lowest precision means the least number of significant figures are taken and the error is greatest.

Answer:

The age of the tree in scientific notation form is \(3.212\times 10^{3}\) .

Option (D) is correct .

Step-by-step explanation:

As given in the question

A tree is 3,212 years old.

Now write 3212 in the scientific notation form .

= 3212

Multiply and divided the above expression by 1000 .

\(= \frac{3212\times 1000}{1000}\)

Simplify the above

\(= \frac{3.212}{1000}\)

Thus it is written as

\(= 3.212\times 10^{3}\)

Therefore the age of the tree in scientific notation form is \(3.212\times 10^{3}\) .

Option (D) is correct .
