Option (D) is correct.

Explanation:

For Aline:

E (v) = Earning * Probability of earning + Don't believe earning * probability

= 200,000 (0.5) + 0 (0.5)

= 100,000

For Saraf:

E (v) = Earning * Probability of earning + Earning * probability

= 0.75 (100,000) + 0.25 (10,000)

= 77,500

Therefore, the expected value of the undertaking is according to Aline, is $100,000.
