Answer: A

Explanation:

* The position property specifies the type of positioning method used for an element (static, relative, absolute or fixed).

absolute: The element is positioned relative to its first positioned (not static) ancestor element

* For absolutely positioned elements, the left property sets the left edge of an element to a unit to the left/right of the left edge of its containing element.

CSS Syntax

left: auto|length|initial|inherit;

length: Sets the left edge position in px, cm, etc.

Incorrect:

position static: Default value. Elements render in order, as they appear in the document flow

Reference: CSS position Property; CSS left Property
