Detailed Solution

Concept- An indicator is something which helps us see that a change has happened and whether a substance is an acid or a base. They are used to detect the pH of a substance.
The indicators which are obtained from nature or natural resources are called natural indicators. But they are not used to check the pH of a substance. Now, we see that China Rose is a natural indicator because it has been derived from nature and it is made by soaking the petals into water for a few hours and the coloured water is used as an indicator to detect whether a substance is acid or base. If the solution turns green, it is a basic solution and if it turns into red then it is an acidic solution.
Hence, the correct option is 3.
