Suppose Gina and Henry Play Two Rounds of the Ultimatum

Suppose Gina and Henry play two rounds of the ultimatum game. In the first round they play for $10; in the second round they play for $1,000. In the first round Gina suggests an 80/20 split ($8 to Gina, $2 to Henry) , but Henry quickly rejects the offer as unfair. Assuming Gina is interested in gaining financially from the experience and that she understands behavioral economics, we would expect her to

A) offer the same relative split ($800/$200) , knowing that Henry will accept the offer because the dollar amount he would forgo by rejecting it is substantial.
B) offer a more unequal split ($900/$100) in order to gain more for herself and figuring Henry will accept the split because $100 is better than nothing.
C) offer a more equal split ($700/$300) to increase the probability that Henry will accept the offer.
D) offer Henry more than half of the pot to ensure acceptance of the offer.
