The question asks the Fermi level LIKELY TO BE(most possible answer).
So even if the acceptor atoms concentration is increased and it reaches 0.1EV, it must first reach 0.28eV.
So if the concentration is increased, then Fermi level will reach 0.28eV and is the most possible answer.

Fermi level of n-type semiconductor is above the valence band if you increase acceptor ions fermi level with is increased that's why Fermil level was close to the valence band.
