The question essentially asks what can we infer from lines 33-35 saying that "superior chess players have exceptional memory for configurations of chess pieces, but only if those configurations are typical of chess games." So if they have exceptional memory only for configurations that are typical of chess games, we can infer that they do not have exceptional memory for some chess piece configurations atypical of chess games, answer choice (D).
Note that we cannot infer anything else with regard to their memory for other factors, sequences, or moves in games other than chess as it is outside the scope of the passage.
