    Equation:

    It contains variables, signs, and equal sign

    for example:

    x+3=y-9

    Expression:

    It does not contain equal sign everything else is same

    now, we will verify each option

    option-A:

    An equation contains variables; an expression never does

    expression can also contain variables

    so, this is FALSE

    option-B:

    An equation contains an equal sign; an expression does not

    So, this is TRUE

    option-C:

    Both expressions and equations contain numbers and/or variables

    so, this is TRUE

    option-D:

    An expression has addition and subtraction; an equation never does

    Equation can have subtraction and addition sign as well

    so, this is FALSE

    option-E:

    An expression involves multiplication, but equations only use addition

    Both can have multiplication and addition

    so, this is FALSE
