Since the table of random digits contains digits in a completely random order, it is possible for five consecutive digits to appear in the table, as in the given entry "11ea938b_5e75_d83b_b4ef_8b1de313d10c_TB5066_00". Option A is not true, as there may be instances where a two-digit number appears more than once in a given row. Option B is false, as it is possible for 00000 to appear in the table. Thus, the correct choice is C.
