Option C
These are the measurements that can be measured without the involvement of any other entity or attribute.
The following direct measures are commonly used in software engineering.
- Length of source code by LOC
- Duration of testing purpose by elapsed time
- Number of defects discovered during the testing process by counting defects
- The time a programmer spends on a program
Source lines of code (SLOC) is alsoknown as LOC.It is a software metric used to measure the size of a software program by counting the number of lines in the text of the program's source code. SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to estimate programming productivity or maintainability once the software is produced.it comes under direct measures.
