Consider the following statements about the Plutonic (intrusive) rocks observed in the field:
1. LACCOLITHS: Vertical to steeply inclined and sheet like body which Cut across the bedding of the rocks in which they intrude.
2. LOPOLITHS: These are basin or saucer-shaped concordant bodies with top nearly flat and convex bottom
3. PHACOLITHS: All intrusive igneous bodies with irregular shape, i.e. the body with no specific shape.
4. CHONOLITHS: These are concordant bodies that occur along the crests and troughs of the folded sedimentary strata.
Which of the above statements are incorrect?

Which of the above statements are incorrect?
The correct option is D 1, 3 & 4
SILLS: Sills are relatively thin tabular sheet like body that penetrates parallel to the bedding planes.
DYKES: Vertical to steeply inclined and sheet like body which Cut across the bedding of the rocks in which they intrude.
LACCOLITHS: It is a concordant body, with flat bottom and convex upward. It is dome shaped.
BATHOLITHS: are the largest kind of plutons, irregular in shape and occupies large area.
LOPOLITHS: These are basin or saucer-shaped concordant bodies with top nearly flat and convex bottom
PHACOLITHS: These are concordant bodies that occur along the crests and troughs of the folded sedimentary strata.
CHONOLITHS: This term is applied to all other intrusive igneous bodies with irregular shape, i.e. the body with no specific shape.
