Option 1 states that the construction sector provided employment to nearly one-tenth of the urban male workforce in India according to the Periodic Labour Force Survey 2017-18. This means that out of all the employed urban males, approximately 10% were working in the construction sector.

Option 2 states that nearly one-fourth of the urban female workers in India were working in the manufacturing sector. This means that around 25% of the employed urban females were engaged in manufacturing jobs.

Option 3 states that one-fourth of the rural female workers in India were engaged in the agriculture sector. This means that approximately 25% of the employed rural females were working in agriculture.

The correct answer, option 2, states that statements 1 and 2 are correct. This means that the first statement about the construction sector employing around one-tenth of the urban male workforce and the second statement about one-fourth of urban female workers being employed in the manufacturing sector are both true according to the Periodic Labour Force Survey 2017-18. However, it does not include the third statement about rural female workers in the agriculture sector.
