Which of the following statements best explains the relationship between the Tropical Easterly Jet (TEJ) and the intensity of the Indian Southwest Monsoon?

Options:

• A: The TEJ is a low-level jet stream that directly pushes the monsoon trough into the Indo-Gangetic plains.
• B: The descending branch of the TEJ over the southern Indian Ocean strengthens the Mascarene High, thereby intensifying the southwest monsoon winds.
• C: The TEJ is formed due to the cooling of the Tibetan Plateau during winter, causing a strong pressure gradient towards the equator.
• D: The presence of the TEJ over the Tibetan Plateau prevents the northward movement of the ITCZ, delaying the monsoon onset.
