Answer:
C. Air pressure is lower between the buildings.
Step-by-step explanation:
As per Bernoulli's equation we know that

so here as we know for same level the value of potential energy per unit volume will be same so here as we change the value of pressure then to compensate the effect of pressure value of the speed of air will increase between two buildings

so here we can say correct answer will be
C. Air pressure is lower between the buildings.
