A tree which is \( 6 \mathrm{~m} \) tall casts a shadow of length \( 4 \mathrm{~m} \) on the ground. At the same time, a flag pole cast a shadow \( 50 \mathrm{~m} \) long. Find the height of the flag pole.
a. \( 75 \mathrm{~m} \)
b. \( 100 \mathrm{~m} \)
c. \( 80 \mathrm{~m} \)
d. \( 125 \mathrm{~m} \)
