Explanation:

As given in figure: 1/N value is close to -0.3
So N will be 1/(-0.3)= -3 (Aprox to this value)
So Arrow A is there.

Please give kudos, if you find my explanation good enough

We see that 1/N is negative, so N is also negative. We also see that 1/N is greater than -1/2; therefore, we have:

1/N > -1/2

N < -2

We see that only A is pointing to a number less than -2; thus, A is the correct answer.

itis drawn to scale. So, we can see n has to be less than -2. Otherwise the indicator will be more nearer to -1. As -3 is only number lesss than -2 its the answer
