Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.
1 meter (m) = 10⁶ micrometers (µm)
Therefore, 1.7 m = 1.7 × 10⁶ µm
Thus, the length of the man compared to the length of the paramecium will be
1.7 × 10⁶ / 85 = 2× 10⁴ .
Therefore, length of the man is 2× 10⁴ times larger than the length of the paramecium.
