Is AB parallel to x-axis? I. OA=\sqrt11 II. B=(2,3)

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

if the statement 1 alone is sufficient to answer the question.

if the statement II alone is sufficient to answer the question.

if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.

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

II.

B=(2,3)

if the statement 1 alone is sufficient to answer the question.
if the statement II alone is sufficient to answer the question.
if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.
if both the statements I and II together are not sufficient to answer the question and additional data is required.

Solution:

I. It gives no information about point B.
∴ I alone is not sufficient.
II. It gives no information about point A.
∴ II alone is not sufficient.
I & II. With

OA=√11

, the location of A with respect to B can’t be uniquely
determined. A can lie anywhere on the circle of radius

√11

∴ I & II together are not sufficient.
