The correct answer is B. Chemists use particle accelerators and lasers in their work.
Explanation: This statement accurately reflects the tools often utilized in chemistry for various experiments and studies. Particle accelerators can help in understanding atomic and subatomic structures, while lasers are used in spectroscopy and other chemical analyses. The other statements have inaccuracies: A is misleading as basic research is systematic; C misattributes the invention of superconducting materials to physicists, as this is a collaborative effort in materials science; and D incorrectly suggests that applied research is solely theoretical, when it typically involves practical applications of scientific knowledge.
