n denotes a number to the left of 0 implies that n is negative and so its reciprocal will also be negative. Hence, the correct answer cannot be D or E, as both of them are positive.
Also it is given that n² < 1/100 implies |n| < 1/10 or -1/10 < n < 1/10, and since n is negative, so -1/10 < n < 0
Now taking reciprocal, -10 > 1/n or 1/n < -10

The correct answer is A.
