.The following expression is true when rnatype is 'ncRNA' and length is at least 200, or rnatype is 'ncRNA' and length is 22:

1. (rnatype is 'ncRNA' and length>=200) or (rnatype is 'ncRNA' and length==22)

What Boolean expression below represents a negation of the above expression?

1. rnatype is not 'ncRNA' and ( length <200 or length != 22)
2. (rnatype is not 'ncRNA' and length < 200) and (rnatype is not 'ncRNA' and length != 22)
3. (rnatype is not 'ncRNA' and length < 200) or (rnatype is not 'ncRNA' and length != 22)
4. rnatype is not 'ncRNA' or ( length <200 and length != 22)
