tengo un problema de optiones que no se como hacer, aver si me podriais ayudar, esta en ingles pero creo q se entiende bien:

C(K) is the price of a European vanilla call option
with the execution (strike) price K. It is known
that C(80) = 10, C(110) = 8, C(120) = 7.
Does it exist here an arbitrage possibility?
If yes, then propose a strategy and draw
the relevant payoff profile. muchas gracias!
