B. In the month of January, 30°C isotherm covers the large part of penisular India.
C. Mahanadi basin region receives rainfall from 100 cm to 200 cm per annum.

Choose the correct answer from the options given below:

Correct option is D

The correct answer is: (d), A and C only
In the month of July, 30°C isotherm covers large parts of north-west India.: This statement is likely correct. The 30°C isotherm typically represents regions experiencing warmer temperatures, and during July, it is expected to cover large parts of north-west India due to the summer heat.
Mahanadi basin region receives rainfall from 100 cm to 200 cm per annum: This statement is likely correct. The Mahanadi basin region, located in central-eastern India, is known for its relatively high rainfall due to the influence of the southwest monsoon. Rainfall in the range of 100 cm to 200 cm per annum is plausible for this region.
Information booster
In the month of January, 30°C isotherm covers the large part of peninsular India.
This statement is incorrect. In January, which is winter in India, temperatures are generally cooler, and the 30°C isotherm is not expected to cover a large part of peninsular India. It would typically cover regions further south, where temperatures are warmer, such as coastal areas.
By 10^th October S.W. Monsoon completes its withdrawal from Indian peninsular region.
The withdrawal of the southwest monsoon from the Indian peninsula typically occurs by mid-October, but the exact date can vary from year to year and from region to region. In some years, the withdrawal may occur slightly earlier or later than October 10th.
