Option C

Step-by-step explanation:

Both balloons are at the same height levels as illustrated in the attached figure.

The horizontal distance between Charlie and balloon A will be given by

$tan50^{\circ}=\frac {1000}{a}\\a=\frac {1000}{tan50^{\circ}}\\a\approx 839.10 ft$

Similarly, the horizontal distance between Charlie and balloon be will be given by

$tan78^{\circ}=\frac {1000}{b}\\b=\frac {1000}{tan78^{\circ}}\\b\approx 212.56 ft$

The horizontal distance of separation between these two balls will be 839.10+212.56=1051.66 ft

Rounded off, this is approximately 1052 ft

Therefore, option C is correct.
