Explanation:

- The 2018 Amendment Act altered the framework within which specific performance is granted.

- Previously, it was a discretionary remedy, but post-amendment, it is generally granted as a rule.

- The exceptions are detailed in sections 11(2), 14, and 16, where specific scenarios are outlined.

- Option 1: Discretionary - This suggests specific performance is subject to judicial discretion, which was the stance before the amendment.

- Option 2: Mandatorily - Under this option, specific performance is the default, barring exceptions.

- Option 3: Both a & b - This implies a mix of mandatory and discretionary aspects, which is incorrect post-amendment.

- Option 4: None of the above - Incorrect as options 1 or 2 contextualize the amendment.

Option 2: Mandatorily is correct.
