The Correct Option is B
Solution and Explanation
Step 1: Understanding pulmonary circulation.
In humans, oxygenated blood from the lungs is carried back to the heart through pulmonary veins.
Step 2: Anatomical detail.
There are two pulmonary veins from each lung, making a total of four pulmonary veins that open into the left atrium.
Step 3: Conclusion.
Hence, the correct answer is (B) 4.
