Explanation:

Let’s break this down:

- Option 1: Express trusts.

These are trusts created clearly and directly by a written or spoken statement. Section 10 definitely applies here.

- Option 2: Implied trusts.

These trusts come about because of the conduct or circumstances—they aren’t clearly stated. Section 10 also covers these.

- Option 3: Trusts created by operation of law.

These arise automatically under the law, like resulting or constructive trusts. Section 10 covers these as well.

- Option 4: All of the above.

Here’s the thing: Section 10 isn’t picky; it covers express, implied, and legal-operation trusts.

The correct answer is Option 4—All of the above. Section 10 applies to all trusts, whatever their origin.
