Question

Are the lines \(l\) and \(m\) parallel? Statements: (I) \(l\) and \(m\) make equal angles with \(y=0\). (II) \(l\) and \(m\) intersect at \(x=0\).

• A. Statement (I) alone is sufficient to answer the question, but (II) alone is not sufficient.
• B. Statement (II) alone is sufficient to answer the question, but (I) alone is not sufficient.
• C. Both the statements (I) and (II) are sufficient to answer the question, but neither statement alone is sufficient.
• D. Both the statements (I) and (II) together are not sufficient to answer the question and additional data are required.

Hint:

If two lines make equal angles with the same axis, their slopes are equal. Equal slopes imply parallel lines.
