Dumping of Iron to the upper ocean can significantly induce the Carbon sequestration in Oceans. This is because introduction of iron to the upper ocean__:

Answer: [B] will stimulate phytoplankton bloom

This question is based upon the concept of Iron fertilization, whereby introduction of iron to the upper ocean to stimulate a phytoplankton bloom is adopted. Like all plants, phytoplankton takes up C02 from air and converts it to carbon compounds like carbohydrates. The plant quickly dies and starts sinking, taking the carbon with it. What happens thereafter is the key to the technique’s efficacy: If it sinks well below the ocean surface, the carbon would effectively have been put away for a long period (Carbon sequestration). This has led to several experiments in recent times.
