With due respect, I'd like to bring in SOF's notice that the diagram in the above question is incorrect. The diagram given above is of the concentration of blood in four men, whereas here, we have asked about the functions of some marked plant parts. I ask SOF to rectify this error,

THAT DOESN'T MAKE SENSE. the diagram has no relation to the questions or the options because the figure of the concentration of oxygen in blood of something but the options and the questions are related to plants. the labels in the diagram are P,Q,R,S meanwhile the labels in the questions areX,Y,Z. There are a lot of errors like this that I am facing nowadays so I would kindly request S O F to please correct these issues ,specially in chapterwise

The needle should point towards South pole because the Earth's North Pole is actually the South pole of a bar magnet. Compass needle always points to the geographical North pole.

The earth's north pole acts like a south pole to the magnet as it attracts the north pole of a magnet (The earth's north pole attracts the north pole of a magnet). This means that the needle of a compass is always the north pole. So, the needle will point to the south pole of the other magnet. In simple words, the North pole of the earth is actually the south pole for a magnet.
