C) very similar or higher

For a heterogeneous test, measures of internal-consistency reliability will tend to be lower compared with other methods of estimating reliability because internal-consistency reliability assumes that all items are measuring the same construct, which may not be the case for a heterogeneous test. As a result, the reliability coefficients may be lower, and other methods such as test-retest or inter-rater reliability may be more appropriate.
