a. oak
b. ash
c. elm
d. poplar
select the best answer from the choices provided a b c d

  c. elm

Step-by-step explanation:

Given : The circumference of the oak tree= 0.539 meters

=   [∵ 1 m = 100 cm]             (1)

The circumference of the ash tree= 0.509 yards

  [∵ 1 yard = 3 feet]

 [∵ 1 foot = 30.48 cm]

       (2)

The circumference of the elm tree = 6281.70 millimeters

         (3)

The circumference of the poplar tree = 0.000385 miles

  [∵ 1 mile = 5280 feet]

 [∵ 1 foot = 30.48 cm]

             (4)

From (1) , (2) , (3 ) and (4) it is clear that

46.54< 53.9 < 61.96 < 628.17

Hence, the elm tree has the greatest circumference.
