All the following condition are favourable for the formation of delta except

A delta is a landform that is created at the mouth of a river when it flows into a standing body of water, such as a sea or an ocean. The formation of a delta requires specific conditions to be present. Therefore, the question is asking which of the following conditions is not favorable for the formation of a delta. The correct answer is "presence of large lakes in the river course." This condition is not favorable for the formation of a delta because a lake has still water, and it will not provide enough force to carry the sediments downstream to form a delta. In contrast, a river flowing into a standing body of water with enough force to transport and deposit sediments creates a delta. Therefore, options "availability of adequate sediments," "absence of strong current at the river mouth," and "presence of sheltered coast" are favorable conditions for the formation of a delta.
