**Core Concept**
The question is testing the student's knowledge of viral classification, specifically the characteristics of non-enveloped single-stranded RNA (ss-RNA) viruses. These viruses have a simple structure, lacking a lipid envelope, and contain a single-stranded RNA genome.

**Why the Correct Answer is Right**
The correct answer is a type of virus that belongs to the Picornaviridae family. These viruses are non-enveloped, meaning they lack a lipid envelope, and have a single-stranded RNA genome. The Picornaviridae family includes viruses such as poliovirus, rhinovirus, and enterovirus, which are known to cause a range of diseases in humans. The lack of an envelope makes these viruses more stable and resistant to environmental factors, but also makes them more easily inactivated by heat and disinfectants.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the correct answer is a specific type of non-enveloped ss-RNA virus, whereas this option is too general.
* **Option B:** This option is incorrect because it refers to a different type of virus, one that is enveloped and has a double-stranded DNA genome.
* **Option C:** This option is incorrect because it refers to a type of virus that is enveloped and has a single-stranded RNA genome.

**Clinical Pearl / High-Yield Fact**
One important point to remember is that non-enveloped viruses, such as those in the Picornaviridae family, are more resistant to environmental factors and can survive for longer periods outside of a host. This makes them more easily transmitted through contaminated surfaces and fomites.

**Correct Answer: C. Norovirus**
