However, none of the responses you provided matches this correct expanded form exactly. But, if we adjust the responses to match the decimals correctly, the closest acceptable response from those listed (considering the form of fractions) is:
(3×100) + (5×10) + (7×1) + (2×1/10) + (5×1/100)
But since this specific response does not exactly match your choices, it may lead to some misunderstanding.
