All of these options can create potential difficulties in the chi square test. 
When sample size is very small, the chi square distribution may not be a good approximation, leading to inaccurate results. 
When sample size is very large, small deviations from expected frequencies may lead to statistically significant results even if the deviations are not practically significant. 
When many cells have expected frequencies of five or less, this violates the assumption of the chi square test and may lead to inaccurate results. Therefore, none of these scenarios are ideal for conducting a reliable chi square test.
