How many women were not recorded in the first draft of the electoral rolls?

The correct option is 40 lakh.

During the preparation of the first draft of the electoral rolls for independent India's first general elections, a significant challenge arose regarding the registration of women voters.
A large number of women were not recorded by their own names but instead registered under descriptions such as "wife of..." or "daughter of...".

The Election Commission refused to accept these entries in such a format and directed that they be registered with their proper names. As a result of this exercise, about 40 lakh (4 million) women who failed to give their proper names were not recorded or ended up being excluded from the first draft of the electoral rolls.
