The first answer is right.
Analyze the picture. Notice the 'rigjt angle symbols'. Those mean lines are perpendicular. You can also use them to determine if two lines are parallel.

Answer:

a) EH ⊥ JG and KF ║ JG

Step-by-step explanation:

In the illustration, a right angle is indicated between lines EH and JG, which means that they are perpendicular to one another. There are two lines crossing DI, KF and JG. Both of these lines cross DI at a 90° angle as indicated by the right angle symbols. This means that these lines run parallel with one another.
