Answer:

Option C.

Step-by-step explanation:

It is given that Stella rewrites −212+3.7 as 3.7−212.

We need to find which property did she use.

According to commutative property of addition,

$A+B=B+A$

Where, A and B are any real values.

In the given expression −212+3.7, A=-212 and B=3.7.

Using commutative property of addition, we get

$(-212)+3.7=3.7+(-212)$

$(-212)+3.7=3.7-212$

So, she used commutative property.

Therefore, the correct option is C.
