Choose the best alternative:

CURRY is to SPICE as ______ is to COLOUR.

Concept:

Functional relationship: Two pairs of words are compared based on how they function or relate to one another.

Explanation:

____ is to COLOUR.

Curry is a dish, and spice is an essential element that adds flavor to it.

Similarly, the blank should be something that is essentially defined or created by color.

Looking at the options:

1. Canvas: A surface where colors can be applied, but it is not directly related to color in the way that spice is to curry.

2. Painting: A painting is something that is created using colors, just as curry is created with spices. This makes Painting 

    the correct analogy, as a painting is defined by its use of color, similar to how curry is defined by the use of spice.

3. Brush: This is a tool used to apply colors but is not analogous to spice in this context.

4. Brightness: This is a characteristic of color, but not something defined by the use of color in the same way a painting is.

Thus, the correct answer is Option 2).
