The 10th Schedule of the Indian Constitution is about which of the following?

The correct answer is Anti-defection. The Tenth Schedule was added by the 52nd Amendment Act, 1985 to curb the practice of legislators switching parties for office or money. A member of Parliament or a State legislature can be disqualified if he or she voluntarily gives up membership of the party, or votes or abstains against the party's direction without its permission. An independent member who joins a party, or a nominated member who joins one more than six months after taking the seat, is also disqualified. The presiding officer of the House decides such cases, subject to judicial review.

The other options are rights found elsewhere. The right to privacy was recognised as part of Article 21 in the Puttaswamy case (2017). Universal adult suffrage is guaranteed by Article 326. The right to education is Article 21A. The 91st Amendment (2003) later tightened the Tenth Schedule by deleting the exemption for a "split" of one-third of a party's legislators, keeping only mergers backed by two-thirds.
