Final answer:

In the Black-Scholes option pricing model, an increase in security volatility will cause a decrease in put value and an increase in call value.

Step-by-step explanation:

In the Black-Scholes option pricing model, an increase in security volatility (s) will cause an increase in call value and a decrease in put value (option B). When security volatility increases, it leads to a higher probability of the underlying asset reaching the strike price, which benefits a call option. However, for a put option, the higher volatility increases the chances of the underlying asset falling below the strike price, reducing its value.
