Which of the following is true about algorithms? a. algorithms can take in a relatively small amount of information as input. b. algorithms are step-by-step rules for reaching a particular solution. c. algorithms are efficient when used by a human brain. d. algorithms have roughly the same efficiency whether used by a human or a computer.

 b) Algorithms are step-by-step rules for reaching a particular solution.

Explanation:

Algorithm is defined as step-vise procedure of solving and gaining a definite answer for a particular problem. The functioning of algorithm is based on inserting data and inputs, altering, processing etc. It is used for evaluating logical and mathematical calculation related with computer field in step by step manner .Other options are incorrect because algorithm can take numerous input for processing.Efficiency of algorithm is maintained by computer for accurate and reliable solutions.Human processed algorithm is not highly precise and systematic.Thus,the correct option is option(b).
