Perform the Indicated Operation Using the Standard Form $$( \sqrt { 7 } + i ) ( 1 + i )$$

Perform the indicated operation using the standard form.​ $$( \sqrt { 7 } + i ) ( 1 + i )$$ ​

A) $( \sqrt { 7 } + i ) ( 1 + i ) \approx 1 + i$
B) ​ $( \sqrt { 7 } + i ) ( 1 + i ) \approx 3.646 - 1.646 i$
C) ​ $( \sqrt { 7 } + i ) ( 1 + i ) \approx 1.646 - 3.646 i$
D) ​ $( \sqrt { 7 } + i ) ( 1 + i ) \approx 1.646 + 3.646 i$
E) ​ $( \sqrt { 7 } + i ) ( 1 + i ) \approx 3.646 + 1.646 i$
