Which statement is true about lamproite relative to kimberlite?

• A. Lamproite is more common than kimberlite
• B. Lamproite is the only rock that transports diamonds
• C. Kimberlite transports diamonds but lamproite does not
• D. Lamproite is rarer than kimberlite, but both transport diamonds to the surface

Answer: (D)

Diamonds reach the surface carried by deep-sourced volcanic rocks, specifically kimberlite and lamproite. Kimberlite is far more common worldwide and has historically provided the majority of mined diamonds. Lamproite, while also capable of carrying diamonds, is much rarer. Because both rock types can transport diamonds to surface environments, the statement that lamproite is rarer than kimberlite but both can bring diamonds up is the correct reflection of their relative abundance and their role in diamond delivery.
