Using the given figure, match the following.

	Column -I		Column -II
\[{{a}_{1}}\]	\[x{}^\circ =\_\_\_\_\]	(p)	\[120{}^\circ \]
\[{{b}_{1}}\]	\[y{}^\circ =\_\_\_\_\]	(q)	\[30{}^\circ \]
\[{{c}_{1}}\]	\[(x{}^\circ +t{}^\circ )=\_\_\_\_\]	(r)	\[50{}^\circ \]
\[{{d}_{1}}\]	\[(z-y){}^\circ =\_\_\_\_\]	(s)	\[170{}^\circ \]
		(t)	\[10{}^\circ \]

A)  \[({{a}_{1}}-r),\,\,({{b}_{1}}-p),\,\,({{c}_{1}}-s),\,\,({{d}_{1}}-t)\]

B)  \[({{a}_{1}}-{{b}_{1}}),\,\,({{b}_{1}}-{{c}_{1}}),\,\,({{c}_{1}}-{{d}_{1}}),\,\,({{d}_{1}}-{{a}_{1}})\]

C)  \[({{a}_{1}}-p),\,\,({{b}_{1}}-r),\,\,({{c}_{1}}-t),\,\,({{d}_{1}}-s)\]

D)  None of these
