Since Charlotte was a girl of high and haughty spirit, she would obviously resent being dominated or overpowered by someone. This brings down our answer options to (1), (2) and (5). But 'in spite' of the claims that the man was making, he was still a stranger. This implies that the claims made by the man were 'unfeigned' or 'genuine', but in spite of that he was regarded as a stranger. 'Specious' means phony or deceptive and does not fit well in the above context and 'fabricated' is to make up (a story, reason, lie, etc.); invent and hence doesn't fit our prediction.
Hence, (2) is the answer.
