Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

-14\dfrac{1}{9}\times -2\dfrac{9}{10}

We first round off the elements one by one :

14\dfrac{1}{9}\\\\=14+0.11\\\\=14.11\\\\\approx 14

Similarly,

2\dfrac{9}{10}\\\\=2+0.9\\\\=2.9\\\\\approx 3

So, Best estimate would be

-14\times -3\\\\=42

Hence, Option 'D' is correct.
