Options
- AA-Q; B-P; C-R; D-S
- BA-P; B-Q; C-R; D-S
- CA-Q; B-P;C-S;D-R
- DA-R; B-P; C-Q; D-S
Correct answer
A. A-Q; B-P; C-R; D-S
Step-by-step solution
- (A) Nuclear reactor: A nuclear reactor is a device used to initiate and control a sustained nuclear chain reaction to produce energy, primarily electrical energy.
- (B) Geiger-Muller counter: A Geiger-Muller counter (P) is a common instrument used for detecting and measuring ionizing radiation.
- (C) Controlled chain reaction: A controlled chain reaction is the process maintained in a nuclear reactor where neutrons released from fission cause further fission reactions, but at a controlled rate to produce energy steadily.
- (D) Critical mass: Critical mass (S) is the smallest amount of fissile material (like uranium-235 or plutonium-239) required to sustain a nuclear chain reaction at a constant rate.
Therefore, the correct mapping is:
(A) (\to Q)
(B) (\to P)
(C) (\to R)
(D) (\to S)
