Correct option is (a) 1 H : 1 V to 1.5 H : 1 V

Explanation: The side slopes of a canal are designed such that they are stable, depending upon the type of soil present in canal area. A canal in cutting is provided with steeper slope than a canal in filing, as the stability of soil is more in case of canal in cutting than in canal in filing.
