Problem $2$

Match the appropriate expression in the right column with each term in the left column.

$(\frac{\text{d}\text{e}\text{l}\text{T}}{\text{d}\text{e}\text{l}\text{v}}{)}_s=$

$q,2.(\frac{\text{d}\text{e}\text{l}\text{u}}{\text{d}\text{e}\text{l}\text{s}}{)}_v=$

$q,3.(\frac{\text{d}\text{e}\text{l}\text{p}}{\text{d}\text{e}\text{l}\text{T}}{)}_v=$

$q,4.(\frac{\text{d}\text{e}\text{l}\text{u}}{\text{d}\text{e}\text{l}\text{v}}{)}_s=$

A$.(\frac{\text{d}\text{e}\text{l}}{\text{d}\text{e}\text{l}\text{v}}{)}_T$

B$.(\frac{\text{d}\text{e}\text{l}\text{s}}{\text{d}\text{e}\text{l}\text{v}}{)}_T$

C$.(\frac{\text{d}\text{e}\text{l}\text{h}}{\text{d}\text{e}\text{l}\text{s}}{)}_p$

D$.-(\frac{\text{d}\text{e}\text{l}\text{p}}{\text{d}\text{e}\text{l}\text{s}}{)}_v$
