Answer:
c) Disagreeing with a project idea while not providing an alternative
Explanation:
Lose - lose negotiation is a term used to describe a negotiation in which both parties cannot agree to a common negotiation, and then it further leads to failure of a contract on both ends, as both do not agree.
In case both parties agree to a negotiation it is termed as win - win negotiation, in which the contract survives, with a positive outlook.
Now, if any party disagree to any component of a project with no alternative, there will be a lose - lose negotiation.
