Answer:

B

Explanation:

Consider the inequality
|x|+19\le 3

Subtract 19 from both sides of inequality:


|x|+19-19\le 3-19\\ \\|x|\le -16

Since the absolute value of the variable x is always non-negative (by definition), then the absolute value of x cannot be less or equal to -16. This means the inequality has no solutions.
