The correct option is C 6x2, 12y2, −3x
In an expression, the terms which contains only numbers are called numeric terms.
In an expression, the terms which contain atleast one variable or combination of variable and number are called algebraic terms.
In the expression, 6x2+12y2−3x−7
6x2, 12y2, −3x are terms containing one or more variables.
Hence, they are algebraic terms.
While -7 is a number so it is a numeric term.
