Answer:
D.
Step-by-step explanation:
[tex]d<4.[/tex]
This inequality does not have ≤ nor ≥. This indicates that when the inequality is graphed on a number line, it will be an open circle.
Using this information, we can eliminate options A, B, and C.
This inequality also indicates that 'd' is less than 4; 4 is greater than 'd.'
Since 'd' is less than 4, the line would go toward the numbers less than 4.
