Answer 1

Option 3 (Inferior lobe) is correct

Justification: The highlighted lobe is the "Inferior lobe" as it is located at the base of the lung, which sits on the diaphragm. Both the lungs contain inferior lobes with similar size. The inferior lobe is present at the lower part of the lung.

Justification for incorrect options:

• Option 1 is incorrect because superior lobe is located at the upper part of the lung. As the highlighted lobe is at the lower part of the lung, it is the inferior lobe but not the superior lobe. So, this option is incorrect.
• Option 2 is incorrect because middle lobe is located between the superior and inferior lobes of the lung (at middle part). As the highlighted lobe is at the lower part of the lung, it is the inferior lobe but not the middle lobe. So, this option is incorrect.
• Option 4 is incorrect because quadrate lobe is not a part of lungs. It is located in the liver. So, this option is incorrect.

Hence, the highlighted lobe in the above picture is option 3 (Inferior lobe).

For better understanding, the highlighted lobe in the picture is labelled and attached below:

Inferior lobe Which lobe is highlighted? superior middle interior quadrate
