Appearance: Affection:: Beauty:

1. Understanding the Relationship: In the given analogy, "Appearance" is related to "Affection." This relationship suggests that one's appearance can evoke feelings of affection or emotional attachment towards them. For example, someone's appearance might influence how much affection or fondness others feel towards them.

2. Finding the Analogy: Now, we need to find a word that mirrors a similar relationship to "Beauty." Beauty is often associated with aesthetic qualities that are visually pleasing or attractive. So, we're looking for a word that is associated with beauty in a similar way that affection is associated with appearance.

Let's analyze the options provided:

- ক (Taste): Taste refers to the sensation of flavor perceived in the mouth. While taste can be enjoyable and pleasurable, it doesn't directly relate to beauty in the same way that affection relates to appearance.

- খ (Fragrance): Fragrance is a pleasant or sweet smell. Like beauty, fragrance can evoke positive feelings and sensory experiences, but the relationship isn't as direct as that between appearance and affection. However, it is the closest match among the options provided.

- গ (Joy): Joy is a feeling of great pleasure or happiness. While beauty can certainly bring joy, the relationship between joy and beauty isn't as direct as that between affection and appearance.

- ঘ (Happy): "Happy" describes a state of being content or joyful. Similar to joy, beauty can contribute to happiness, but the relationship between happiness and beauty isn't as direct as that between affection and appearance.

3. Selection and Justification: While none of the options perfectly mirror the relationship between appearance and affection, option খ (Fragrance) is the closest match. Fragrance, like beauty, can evoke positive feelings and sensory experiences, although the relationship isn't as strong as that between appearance and affection. Therefore, based on the options provided, খ (Fragrance) is the most appropriate choice for completing the analogy.

So, by analyzing the relationships and considering the options, we can conclude that option খ (Fragrance) best fits the analogy "Appearance: Affection:: Beauty:."
