While researching a topic, a student has taken the following notes: platinum is a rare and expensive metal. it is used as a catalyst for chemical reactions. platinum catalysts typically require a large amount of platinum to be effective. researcher jianbo tang and his colleagues created a platinum catalyst that combines platinum with liquid gallium. their catalyst was highly effective and required only trace amounts of platinum (0.0001% of the atoms in the mixture). the student wants to explain an advantage of the new platinum catalyst developed by jianbo tang and his colleagues. which choice most effectively uses relevant information from the notes to accomplish this goal?
a) It reduces the cost of catalytic reactions due to the reduced amount of platinum required.
b) It increases the reaction rate of catalytic reactions due to the addition of liquid gallium.
c) It expands the range of reactions that platinum catalysts can perform.
d) It improves the durability of platinum catalysts due to the combination with liquid gallium.
