Answer:

D. 135°

Step-by-step explanation:

Time is 1:30

The minute hand traveled half of full circle

The minute hand position is:

360°×1/2= 180°

The hour hand traveled 1.5 hr ÷ 12 hr= 1/8 of full circle

The hour hand position is:

360°×1/8= 45°

the difference between the hands:

180°-45°= 135°

Choice D. 135° is the correct one
