Seniors, whose opinions I value, have supported the cause.
1. We basically use the word "whose" to initiate a relative clause signifying possession by things, animals, and people.
2. It is used to question which individual owns or is responsible for someone or something.
3. Let us take some examples-
* Rony works with another colleague whose name I forgot.
* Birley has a 15-year-old son whose ambition is to be a cricketer.
* This is the novel whose abstract I couldn't remember.
