Explanation:

- Statement I tells us that two taps can fill the tank in 6 hours. This alone doesn't tell us how long one tap will take individually or how they interact with the emptying tap.

- Statement II says one tap can empty the tank in 14 hours. This alone doesn't provide information on the filling taps.

- Since neither statement provides complete information on its own about the individual rates of the taps that fill, neither can answer the question alone.

- Even when combined, the statements do not give individual rates for each filling tap, thus we cannot solve for how long the tank will take to fill completely.

Option:4 is correct: Both statements together don't give enough information to solve the problem.
