Answer:
d. If Cazden's stock price rose by $5, the exercise value of the options with $25 strike price would also increase by $5.
Step-by-step explanation:
A call option confers a right, not an obligation upon the call buyer to buy a security at a pre determined price, known as exercise price or strike price at a future date.
A call buyer would exercise his right only in the scenarios wherein the strike price is lesser than the current market price on maturity.
Profit of a call buyer is given by = CMP as on expiry - Exercise/Strike price - Option premium paid
wherein CMP= Current Market Price
A call option is "in the money" when it's strike price is less than it's current market price. In the given case, it means if the CMP today represents CMP upon expiry, call buyer would exercise his right and his gain would be $5 i.e $30 - $25.
Since the $25 exercise option is "in the money", an increase in stock price by $5 will also increase the strike price by $5.
