When a parcel of air is considered "saturated", the relative humidity of that parcel of air is . A) 100% or more B) 75% C) 50% D) Less than 100%

100%, rarely falls below 30%. So I would say D) Less than 100%.

Water flows along the east coast and across the western tropical pacific towards south america, while they both are directed towards that way,  el niño does not directly affect the southern flow of water along the coast.
