Answer: Fourth option is correct.

Explanation:

Since we have given that

Measure of AE = 86

Measure of BD = 40

We need to find the measure of ∠BKD.

Since we know that the central angle is the average of measures of two intercepted arc of this angle.

So, it becomes,

$m\angle BKD=(AE+BD)/(2)\\\\m\angle BKD=(86+40)/(2)\\\\m\angle BKD=(126)/(2)\\\\m\angle BKD=63^\circ$

Hence, ∠BKD = 63°

Therefore, Fourth option is correct.
