Question A
Correct option is (iii) sought after, as it is indicated in the passage that "I was overwhelmed with gratuitous advice". Gratuitous means not required, or not necessary. Hence the author was not asking for advice, it was not sought after
Question B
Correct option is (iv) when he was on the steamer. It is indicated at the end of the passage that "The fellow passengers in the steamer began to advise us". After reading the statement, "I should want them after leaving Aden", you might feel that the correct option could be (ii) when he was in Aden, but the passage doesn't give enough information to confirm that the advice was give at the point when he was in Aden
Question C

With bioengineered foods, you risk ingesting chemicals that are foreign to your body. If you ingest too much of the chemicals, your own body could be changed. For example, you have a natural orange. Scientists want to make your natural oranges bigger and sweeter, so they modify the DNA of the orange. With the modified DNA the new orange changed how it grew, increasing the number of natural chemicals (chemicals created by the orange to grow) it created. These chemicals are ingested by you, the consumer, and after eating your new oranges for a year every day, you notice you may have fertility issues, increased aging, etc. By eating bioengineered foods, you can find changes in your body that wouldn't have occurred if you stuck to that natural orange.
Hope this isn't too long and confusing.
