Explanation:

1 only

The MJO creates favorable conditions for tropical cyclone activity: This statement is correct. The Madden-Julian Oscillation (MJO) is a phenomenon characterized by the eastward movement of large regions of atmospheric circulation and cloudiness across the tropics, and it can enhance the conditions favorable for tropical cyclone development.

It always delays the onset of the Monsoon season around the globe: This statement is incorrect. The MJO does not always delay the onset of the monsoon season. Its impact on the monsoon is complex and can vary, but it is not a consistent delaying factor.

MJO also causes the phenomenon El Niño: This statement is incorrect. The Madden-Julian Oscillation (MJO) and El Niño are distinct phenomena. El Niño is associated with the periodic warming of sea surface temperatures in the central and eastern equatorial Pacific, while the MJO is a different atmospheric phenomenon related to the eastward movement of large-scale patterns of atmospheric convection.

Therefore, the correct answer is Option 2: 1 only.
