Answer:
The statement that is NOT true is b || d
Explanation:
To solve this question, I recommend drawing out all of the lines. For example, if you know A and B are perpendicular to each other, draw two lines that are perpendicular, and label them A and B. Then, the question says B is perpendicular to C, so draw a line perpendicular to line B and label it C.
Do this for all of the lines, then you will see that the statement "b is parallel to d" is not true.
