An angle is more than $$45^o$$. Its complementary angle must be less than $$45^o$$.
Correct option is A. True
Let $$x$$ and $$y$$ are two angles making a complementary angles, and $$x$$ is greater than $$45$$ degrees.
$$\Rightarrow \ x+y=90^o$$
$$\Rightarrow \ y=90^o -x$$.
As $$90=2\times45$$.
Therefore, $$y$$ will be less than $$45$$ degrees.
Hence, given statement is true.
Therefore, option $$A$$ is correct.
