Answer:
The star to I should travel if I need to travel to 13°N latitude and 75°E longitude is:
C. Star C.
Explanation:
As you can see in the image provided, the latitude is expressed from south to north every 10°, so the coordinate of 13° N latitude must be found somewhere between 10° N and 20° N, on the other hand, the longitude is express from left to right, with 10 ° lapses, so the 75° E coordinate is exactly in the middle, between 70° E and 80° E, so the only star that applies to those coordinates is the star C.
If you want to prove this analysis, you can take into account that to the city to which you would go is Mangalore in India, I attached an image where the said city is referenced within Asia and you will see that the star C is located in the same place where the city of Mangalore is located.
