Solution

The correct option is A higher than
According to Bernoulli's principle, in a fluid that flows horizontally, the points having greater speed will have lower pressure.
That is, if $v_{A} > v_{B}$ , then $P_{A} < P_{B}$ ,
$v_{A} :$ Speed of air at point A
$v_{B} :$ Speed of air at point B
$P_{A} :$ Pressure at point A
$P_{B} :$ Pressure at point B
