Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Q31. Which of the following statements in relation to the solar system is/are correct? (Multiple Select Question) (A) The most abundant elements are H and He. (B) The abundances of elements with atomic numbers 1-50 show an overall decreasing trend. (C) The abundances of heavier elements (atomic number>50) are mostly higher than that of lighter elements (atomic number <50). (D) Elements having odd atomic numbers are more abundant than their immediate neighbours.

As you can see option A and B is correct from the graph given but option C is wrong because abundance of heavier metals is actually lesser than lighter metals and in case of option D elements having even atomic number are more abundant than the intermediate neighbours and not the other way around

Correct answer should be (A, B). As it is well known that our solar system mostly comprises of Hydrogen and Helium (Jovian planets like Jupiter, Neptune have great amount of hydrogen and helium). Even your primitive Or primordial solar system has great Or ample amount of these two gases. So, A is correct. B is correct and you can find this from the logarithmic abundance and atomic number graph (which I have attached with the answer). C is not correct, as you might be knowing already that there is overall decreasing trend and solar system mostly consists of elements of lower atomic numbers rather than going for the higher ones. D is also correct, as simply Nitrogen being less abundant than it's immediate neighbour Oxygen(which is present in calculative amount).
