Which of the following are three key commodities often focused on by recruitment consultants?

The correct answer highlights oil, natural gas, and metals as three key commodities due to their significant roles in the global economy and various industries. Oil and natural gas are foundational energy sources, powering transportation, heating, and electricity generation worldwide. Their fluctuations in supply and demand can have substantial economic impacts, making them crucial for recruitment consultants focusing on energy and commodities sectors.

Additionally, metals like copper, aluminum, and others are vital for numerous applications ranging from construction to electronics. The demand for metals is driven by industrial growth and technological advancement, which is why recruitment in sectors dealing with these commodities remains strong.

The other options include commodities that are important, but do not have the same level of universal economic impact as oil, natural gas, and metals. For instance, although copper, lithium, and gold are valuable, they represent a more niche area compared to the broader energy and metals landscape represented in the correct answer.
