If $$a \neq b$$ and $$c \neq d$$, what is the value of $$\frac{a^2 + d^2}{b^2 + c^2}$$?
I. $$\frac{a + b}{c - d} = \frac{c + d}{a - b}$$
II. $$ad \neq bc$$

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.
