Which of the following option sensitivities measures the change in the price of the option with respect to a decrease in the time to expiration?

A)
Theta.

B)

For a change in which of the following inputs into the Black-Scholes-Merton option pricing model will the direction of the change in a put’s value and the direction of the change in a call’s value be the same?

A)
Exercise price.

B)
Volatility.

C)
Risk-free rate.

A decrease/increase in the volatility of the price of the underlying asset will decrease/increase both put values and call values. A change in the values of the other inputs will have opposite effects on the values of puts and calls.
