Answer:
long 1 ABC Jan 75 Call
Step-by-step explanation:
This type of customer (or investor) is bearish about the market, i.e. he/she believes that the stock prices will drop. The investor will try to create a net credit position (the credit spread = $75 - $65). The maximum possible profit is created when the stock price falls below $65, and the maximum possible loss would occur if the price went above $75. This investor is a net seller, since it is a short call spread.
