Which of the following is not error in the given BASIC statement 40 C + D = 4(H1 + J) + -2 * F
1) The left side of an assignment statement must have a single identifier and not a calculation as C+D
2) The expression 4(H1 + J) is missing a multiplication sign i.e. it must be 4*(H1+J)
3) The identifier name H1 is not permitted in Basic
4) Two consecutive operations (i.e. + -2) are not acceptable
