The method used for data cleaning from the options provided is b. Data filtering.

Here's a brief explanation of each term:

a. Data mining: This is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.

b. Data filtering: This is the process of choosing a smaller part of your data and only using that subset for viewing or analysis. It is indeed a method used in data cleaning to filter out irrelevant or inaccurate data.

c. Data encryption: This is the process of converting data into a code to prevent unauthorized access.

d. Data scaling: This is a step in data preprocessing that is applied to independent variables or features of data. It basically helps to normalise the data within a particular range. Sometimes, it also helps in speeding up the calculations in an algorithm.
