Explanation

Option D is correct because the "femoral ligament" does not exist as an anatomical structure - it is a fabricated term designed to test whether students can distinguish real contents from an imposter. The femoral triangle's three main contents are the femoral nerve, femoral artery, and femoral vein (A, B, and C), all of which pass beneath the inguinal ligament into this space, making them legitimate distractors. The inguinal ligament forms the superior boundary of the triangle but is not a content within it, and no structure called the "femoral ligament" is recognized in anatomy.

Memory tip: Use the mnemonic NAVY to recall the contents from lateral to medial - Nerve, Artery, Vein, Y (the femoral canal/empty space with lymphatics). If you see a term like "femoral ligament" on an exam, flag it immediately - the key ligament here is the inguinal ligament, which is a border, not a content.
