Explanation:
GPS stands for global positioning system in which the satellite sends information regarding position any individual, place or thing in terms of bearings (latitude and longitude) with respect to time. There are total 24 satellites that rotate around the earth twice with in a period of 24 hours and hence are capable of locating the position of any object more accurately as compared to compass.

Answer:
The correct answer is D.
Explanation:
We can rule out cotyledon because it is the embryonic leaf of the seed and it doesn't take part in phototropism.
Which part of the coleoptile is responsible for phototropism can be derived from empiric data by preventing some parts of the coleoptile to recieve light. In this case preventing the tip of coleoptile prevents photostrism movement so correct answer is D (see figures).
