Concept:Use the fixed neighbours around Kartik, Jiya and Neelu, then place the remaining three persons using Heena’s clue.
Explanation:Jiya is a neighbour of both Kartik and Neelu, so Jiya must sit between Kartik and Neelu.
Pranav is on Kartik’s immediate right.
Therefore, Jiya sits on Kartik’s left, and Neelu sits on Jiya’s other side.
Layra is second to the left of Heena.
Heena is not sitting between Pranav and Mayra.
Using these clues, the circular order becomes Pranav, Kartik, Jiya, Neelu, Heena, Mayra, Layra, and then back to Pranav.
From this order, Heena and Neelu are adjacent to each other.
Layra and Kartik are not adjacent.
Mayra and Pranav are not adjacent.
Neelu and Mayra are not adjacent.
Answer:Heena and Neelu are sitting adjacent to each other.
Therefore, the correct option is D.
