Answer: B. $H_0:p_1=p_2$

$H_a:p_1>p_2$

Step-by-step explanation:

Let $p_1$ be the proportion of all U.S. adults that smoked in 1995. Let $p_2$ denote the proportion of all U.S. adults that smoked in 2000.

Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.

i.e. $p_1>p_2$

Alternative hypothesis $(H_a)$ is the statement containing population parameter that shows there is significant difference between the groups being tested.

⇒ $H_a:p_1>p_2$

Null hypothesis $(H_0)$ is the statement containing population parameter that shows there is no significant difference between the groups being tested.
