As per Section 68 of The Companies Act, 2013, the company cannot buy their own shares from which of the following source:

Registrar of the company

Correct answer: Option (3) → Registrar of the company

Concept: Sources for buy-back of shares under Section 68 of the Companies Act, 2013, from Accounting for Share Capital.

Section 68 permits a company to buy back its own shares from its existing shareholders on a proportionate basis, from the open market, from odd-lot holders, and from employees to whom shares were issued (ESOP/sweat equity). The Registrar of the company is a regulatory authority, not a shareholder, so shares cannot be bought back from the Registrar. Hence Option (3).
