The question is referring to primary succession, which begins with the colonization of living organisms in an area that hasn't had any living organisms before.
This kind of succession begins with microorganisms, and plants such as lichens and mosses.
Given that a rock outcrop is a terrestrial environment, lichens (C) are most likely to be the firsts organisms.
Answer: Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic.

Answer:
The correct answer is: Social.
Explanation:
- In reference to marketing, Value can be defined as the preference which a customer shows towards one commodity, say A, after analysing and comparing the cost to benefit ratio of the commodity A when compared to another commodity, say B.
- The customer tends to choose commodity A over commodity B only when he gets better benefit from the commodity A as compared to commodity B.
- Value can be divided into four categories:
- Functional Value: Here the customer benefits from the purchase of a commodity as the commodity provides a solution to the customer's need.
- Monetary Value: Here the customer chooses to buy a commodity after getting attracted to the cheaper price at which the commodity is available. This commodity may or may not be beneficial to the customer.
- Social Value: Here the customer chooses to buy a commodity that allows the customer to connect or link with others.
- Psychological value: Here the customer buys a commodity that appeals to his senses and makes him feel good.
- In the given question, as the elimination of "dead zones" in mobile networking area improves the connectivity among people, so this is an example of Social Value.
