The answer to your question is Option C [120000J].

Hey mate after reading your question we come to know one concept tha t is ,

Energy = Power × time .

Here,Energy is product of both the power and time taken .

So,According to Th is concept lets apply it to your question

But one thing that is we should convert time to minutes So,

Time = 20 × 60 = 1200seconds .

Then,Applying it to the formula we get,

Energy = 100W × 12000sec

Energy = 120000J.
