Two resistances \[{{R}_{1}}\] and \[{{R}_{2}}\] are joined as shown in the figure to two batteries of e.m.f. \[{{E}_{1}}\] and \[{{E}_{2}}\]. If \[{{E}_{2}}\] is short-circuited, the current through \[{{R}_{1}}\] is [NDA 1995]

• A.                    \[{{E}_{1}}/{{R}_{1}}\]
• B.                    \[{{E}_{2}}/{{R}_{1}}\]
• C.                    \[{{E}_{2}}/{{R}_{2}}\]
• D.                    \[{{E}_{1}}/({{R}_{2}}+{{R}_{1}})\]
