Option 1: Voluntary acquisition of citizenship of a foreign country is a condition for the disqualification of a Member of Parliament. If a member acquires citizenship of a foreign country voluntarily, they are no longer eligible to hold a seat in Parliament.

Option 2: Holding the office of the Chairperson of the National Commission for Women is not a condition for the disqualification of a Member of Parliament. This means that a Member of Parliament can simultaneously hold the position of the Chairperson of the National Commission for Women without facing disqualification.

Option 3: The Member abstaining from voting in the House without prior permission is a condition for disqualification. It is important for Members of Parliament to actively participate in the voting process and abstaining without prior permission can lead to disqualification.

Option 4: The Member holding the office of the Chairman of the Board of Directors of the National Coal Development Corporation Ltd is not a condition for disqualification. This means a Member of Parliament can simultaneously hold this position without facing disqualification.

Therefore, the correct answer is option 2 as it does not meet the criteria for disqualification of a Member of Parliament.
