A)2
B)5
C)10
D)a value determined by multiplying the marginals

To ensure the validity of the chi-square test, the expected frequency of any cell in a contingency table should not be less than 5. While a minimum of 2 is the general rule for larger tables (more than 2x2), in smaller tables, a value less than 5 can lead to inaccurate results. The other options are not correct because there is no set rule for determining minimum expected frequency based on the marginal totals, and multiplying the marginals is not a reliable way to determine minimum expected frequency.
