(b). lakhs
(c). thousands

Answer 1

Hint: Recall the Indian number system and the different periods it consists of. Then write under which period does ten lakhs come under.

Complete step-by-step answer:
There are different numbering systems to represent the numbers. The International Numbering system and Indian numbering system are the most common and widely used.
In the International numbering system, the numbers are grouped into three digits each and given period names as ones period, thousands period, millions period, etc.
In Indian numbering system, different periods like ones, thousands, lakhs, crores, etc. are used. It includes ones (1), tens (10), hundred (100), thousands (1,000), ten thousand (10,000), lakhs (1,00,000), ten lakhs (10,00,000), crores (1,00,00,000), ten crores (10,00,00,000) and so on.
The first period is called the ones period and is formed by the first three digits of the number from the right.
The second period is called the thousands period and is formed by the next two digits of the number.
The third period is called the lakhs period and is formed by the next two digits of the number.
The fourth period is called the crores period and is formed by the next two digits of the number.
Also, we have to use commas after every period to differentiate the periods.
We can therefore conclude that lakhs belong to Indian numbering system.
Hence, ten lakhs come under the third period of the Indian numbering system, that is, lakhs period.
Hence, the correct answer is option (b).

Note: Ten lakhs is also equal to one million in International number system, so you might choose option
