(C) 200,000
(D) 600,000
(E) 900,000


Assembly Machine A produces 2000 units in one hour. So in 15 hours,it will produce 2000*15 = 30,000 units.
Similarly Assembly machine B being thrice as efficient will produce 30,000*3=90,000 units in 15 hours per day.
In 10 days, Machine B will therefore produce 90,000*10=900,000 units in 10 days.

Thus,E is the correct answer choice.
