A six-month European call option's underlying stock price is $86, while the strike price is $80 and a dividend of $5 is expected in two months. Assume that the risk-free interest rate is 5% per annum with continuous compounding for all maturities.

1) What should be the lowest bound price for a six-month European call option on a dividend-paying stock for no-arbitrage?

2) If the call option is currently selling for $2, what arbitrage strategy should be implemented?
