(a) extrusive igneous rock
(b) intrusive igneous rock
(c) metamorphic rock
(d) sedimentary rock

Option (D)

Explanation:

The sedimentary rocks are the rocks that are suitable for the trapping of oil and natural gases. These are found to be present in the pore spaces of the rocks below the surface of the earth that are formed at different pressure and temperature conditions. The natural gases that are present in the interconnected pore spaces are methane, ethane, propane, and butane and they are basically found in association with the natural gases that collectively form the oil.

Some examples of sedimentary rocks that comprise these gas and oil are sandstone, limestone, and shale. These rocks are a type of reservoir that stores these fossilized products.

Thus, the sedimentary bedrocks contains these oil and gas deposits.

Hence, the correct answer is option (D).

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.

the answer is the last option or letter d)
