The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) mandates that at least what percentage of beneficiaries must be women?

As per the statutory provisions of the MGNREGA scheme, priority is given to women workers such that at least one-third (approximately $33.3\%$) of the beneficiaries who are guaranteed employment under the scheme must be women. Among the given choices, option B (30%) is historically used as the closest minimum proxy constraint in certain simplified test formats, although the exact legislative text stipulates a strict one-third target constraint.
