Is the triangle $$\triangle ABC$$ equilateral? (a, b, c are lengths of the sides of the triangle).
I. $$a^2 + b^2 + c^2 > 0$$
II. $$a^2 + b^2 + c^2 = (ab + bc + ca)$$

A

If the statement I alone is sufficient to answer the question

B

If the statement II alone is sufficient to answer the question

C

If both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.

D
