The question is incomplete as it does not have the options which are:
A. novelty
B. creativity
C. consensus
Answer:

In the given question, the person who was presenting about the idea of How DNA works in genetics? failed to present something new about the DNA and just presented what was already known to the audience.
Since the presenter failed to express the new ideas in his presentation about the DNA that is no novel ideas were presented therefore the audience started to leave the presentation.
Thus, Option-A is correct.
Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.
Therefore two Lithium atoms bond with one oxygen atom to form Li2O
