Ok so in basic terms, ad hominem is attacking your opponent and not there position. An example would be:
You cannot believe my opponent; his hair is untidy and his visage is beyond unprofessional.
By saying that the opponent is "untidy and unprofessional", you are attacking his character. Rather than arguing against his position, the attack of the opponent's character is Ad hominem.
I hope this helps :-)
No man thinks more highly than I do of the patriotism, as well as abilities, of the very worthy gentlemen who have just addressed the House. But different men often see the same subject in different lights; and, therefore, I hope it will not be thought disrespectful to those gentlemen if, entertaining as I do opinions of a character very opposite to theirs, I shall speak forth my sentiments freely and without reserve. This is no time for ceremony. The questing before the House is one of awful moment to this country. For my own part, I consider it as nothing less than a question of freedom or slavery; and in proportion to the magnitude of the subject ought to be the freedom of the debate. It is only in this way that we can hope to arrive at truth, and fulfill the great responsibility which we hold to God and our country. Should I keep back my opinions at such a time, through fear of giving offense, I should consider myself as guilty of treason towards my country, and of an act of disloyalty toward the Majesty of Heaven, which I revere above all earthly kings.
The answer is A.

Speak about how the world has evolved through the topics of science and technology (separately)
Discuss the fact that 40 years ago computers weren't invented and now they are beyond the capacity of a human brain.
Discuss how science nowadays has been able to uncover mysteries of the earth as well as how science has created (in cooperation with technology) robots.
Basically discuss how it has changed over the years, the importance of technology in the changing world as well as science.
