To change the left margin of an element, you can use the CSS property margin-left. This property allows you to specify the amount of space between the left edge of the element and its surrounding content.

Let's go through each option to understand why it is correct or incorrect:

Option A) indent - This option is incorrect because the indent property is used to specify the indentation of the first line in a block of text. It does not affect the margin of an element.

Option B) text-indent - This option is incorrect because the text-indent property is used to specify the indentation of the first line in a block of text. It does not affect the margin of an element.

Option C) margin-left - This option is correct because the margin-left property allows you to change the left margin of an element. By specifying a value, you can increase or decrease the amount of space between the left edge of the element and its surrounding content.

Option D) margin - This option is incorrect because the margin property is a shorthand property that allows you to set the margin on all four sides of an element at once. It does not specifically target the left margin.

The correct answer is C) margin-left. This option is correct because it specifically targets the left margin of an element.
