a. Mid-July
b. Mid-September
c. Mid-June
d. Mid-May

Answer 1

Hint: The Arabian sea branch reaches Mumbai about 10 days later on approximately 10th June and then moves towards saurashtra-kachchh and the central part of the country. It meets the other branch of monsoon over the plains.

Complete answer: The monsoon winds are pulsating in nature and can be affected by different atmospheric conditions on their way. The monsoon begins from early June and lasts mid September.
 When monsoon arrives, there is a sudden increase in the normal rainfall and it continues constantly for several days and is called a burst of monsoon. It can be distinguished from pre monsoon showers.The southwest monsoon reaches the southern tip of India in the first week of June.
 From there, the south west monsoon divides into two branches: the Arabian Sea branch and the Bay of Bengal branch.
-The Arabian Sea branch reaches Mumbai and central parts of the country about ten days later from 10th of june. The Bay of Bengal branch reaches Assam and gets deflected towards west to the ganga plains due to lofty himalayas. The Arabian Sea branch reaches saurashtra-kachchh by mid June.
-The Bay of Bengal branch and the Arabian Sea branch merge over the northwest of ganga plains.

Looking at the options given:
Option a: By mid-July, the monsoon extends to Kashmir and the remaining parts of the country. It is an incorrect answer.
Option b: The Arabian Sea branch of monsoon does not arrive saurashtra-kachchh by mid-September. It is an incorrect answer.
Option c: The Arabian Sea branch of monsoon arrives saurashtra-kachchh by mid-June. It is the correct answer.
Option d: By mid-May, the monsoon arrives in Andaman and Nicobar Islands. It is an incorrect answer.

Hence, Option ‘c’ is correct.

Note: Do not confuse it with the Bay of Bengal branch that moves towards northwest of ganga plains after deflecting from himalayas in the assam. It meets the Arabian sea branch over northern plains.
