A
squnch joint

D

AI Explanation
The correct answer is B) liner. A liner is a casing string that is run below the previous casing string but does not extend to the wellhead. This is in contrast to a production string, which does extend to the wellhead. Liners are commonly used in oil and gas wells to provide additional structural support and zonal isolation at lower depths in the well. The other options, such as a squnch joint or a packer, are not accurate descriptions of this type of casing string.
