The correct answer is D. consolation.
Kamal’s friends had nothing to offer him other than consolation in his grief. This means that they were there to support him and offer him comfort during his time of sadness. They could not offer him a solution to his grief, as there is no easy answer to losing a loved one. They could not offer him happiness, as he was clearly not in a happy state. They could not offer him kindness, as they were already being kind by being there for him. And they could not offer him friendship, as they were already his friends. Therefore, the only thing they could offer him was consolation.
Consolation is the act of providing comfort or support to someone who is grieving. It can be done in many ways, such as listening to the person, offering words of encouragement, or simply being present with them. Consolation can be a very important part of the healing process for someone who is grieving.
In the case of Kamal, his friends were able to offer him some consolation by being there for him and listening to him. They could not offer him a solution to his grief, but they could offer him their support. This was likely very helpful to Kamal during his time of sadness.
