Answer:
a. lycophytes is the correct answer.
Explanation:
Microphylls are found in lycophytes.
lycophyte is a vascular plant, they have a unique type of leaves called microphylls.
The lycophytes belong to the division of Lycophyta, they are seedless plants and have vascular tissue.

There are different causes to error in measurement, most common are instrument precision and misreading the measurements. Some cases are from the experimenter judging to what they want rather than the reading itself.(no offense)
But... measurements are never accurate anyway, they're all estimations.
You may talk about this picture:
A: it is an
ionic bond (which is a strong interaction, between two close atoms which has a large difference in their charges, like azote and oxygen)
B: is a
hydrogen bond (between O in a side and H in the other side)
C: it could be a
Van der Waals bond (small interaction between Carbon and hydrogen from different sides (London interaction))
D:
Hydrogen bond (between the Oxygen and hydrogen from different sides)
E: it's an
ionic bond
D is the correct answer :)
