What is the score that you would receive if the test contained no error?

A) observed score
B) actual score
C) true score
D) error score

The score that would be received if there were no error is the true score, as it represents the actual level of knowledge or performance without any external factors influencing the result. The observed score may be affected by various sources of error, such as measurement error or test-taking conditions, while the actual score and error score are not typically used in this context.
