Base on the Bernoulli’s Principle, when air flow passes through a venturi tube, the air flow will:

constrict, increase in speed and reduce in pressure

expand, increase in speed and reduce in pressure

expand, reduce in speed and increase in pressure

constrict, reduce in speed and increase in pressure

In parasite drag, form drag refers to:

Airflow that flowing around the aircraft like engine cowlings, antennas

The intersection of airstreams that creates turbulence
