The correct answer is option 'D': the Camel went on looking at his own reflection in the water.

Explanation:

When the Djinn went to the Camel, the Camel's response was to continue looking at his own reflection in the water. This behavior of the Camel reveals its vanity and self-absorption. The Djinn was hoping for some kind of response or acknowledgment from the Camel, but instead, the Camel ignored the Djinn and remained focused on itself.

The story of the Djinn and the Camel is actually a fable called "The Camel's Nose" or "The Nose of the Camel," which is a cautionary tale about the consequences of giving in to small requests that can eventually lead to much bigger and unfavorable outcomes.

In the fable, the Djinn asked the Camel if he could put his nose into the Camel's tent, as the Djinn was seeking shelter from the cold. The Camel, without thinking much of it, allowed the Djinn to put his nose inside. However, once the Djinn's nose was in the tent, he gradually pushed more and more of his body in until he completely took over the Camel's space.

This behavior of the Djinn symbolizes the concept of gradual encroachment or taking advantage of someone's kindness or generosity. The Camel's initial willingness to accommodate the Djinn's small request ultimately led to losing his own space and comfort.

In the context of the given options, it is clear that the Camel's response of looking at its own reflection in the water aligns with the fable's narrative. The Camel's self-absorption and lack of attention to the Djinn's presence ultimately led to its own downfall.

Overall, the correct answer option 'D' is the most appropriate because it accurately reflects the behavior and consequences depicted in the fable of "The Camel's Nose."
