Organic soil is never above A-line. So option c is wrong.

Above A line and liquid limit is > 35% CI (clay with intermediate comprehensibility) occurs. So, option D is right.

Above A-line clay soil classification is done and below A-line organic/silt classification is done. So, option (D) is correct.
