The statement that is false about base stacking is; B. Stacking interactions are hydrophilic in nature.
<h3>What is the truth about Base Stacking?</h3>
Base stacking is defined as a common arrangement of nucleobases that are found in the three dimensional structure of nucleic acids. Bases (or base pairs) are planar, and these planes stack at contact distance , excluding water and maximizing Van der Waals interactions.
Looking at the given options, the only one that can be said to be false about the defined base stacking above as regards nucleic acids is option B.
The missing options are;
A. Stacking interactions occur when two or more bases are positioned with their rings parallel to each other.
B. Stacking interactions are hydrophilic in nature.
C. Stacking involves a combination of van der Waals and dipole-dipole interactions between bases.
D. Base stacking helps to minimize contact of the bases with water.
E. Base stacking interactions are important in stabilizing the three-dimensional structure of nucleic acids.

The best answer is D
A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
