Can someone me with this question .

It looks like the answer you chose is correct.

The word "conservative", as defined by Dictionary.com, just means this:

disposed to preserve existing conditions, institutions, etc., or to restore traditional ones, and to limit change; cautiously moderate or purposefully low

That means that anything that's "conservative", whether economic, political, environmental, etc., just seeks to limit change or is carefully moderate (opposed to liberal, which means progressive or lavish).
