In a triangle $$ABC, \angle B = 90^\circ$$. Then what is $$AB : BC : CA ?$$

I. $$\tan C = \frac{1}{2}$$

II. $$\sin^2 A + \cos^2 A = 1$$

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

if both the statements I and II together are not sufficient to answer the question and additional data is required.
