**Core Concept**
The question is testing the student's knowledge of the types of sensory modalities and their corresponding nerve fibers. Touch is one of the primary sensory modalities, and it is mediated by specific types of nerve fibers that transmit signals from the skin to the brain.

**Why the Correct Answer is Right**
Touch is carried by A-delta (Aδ) and C-fibers, which are types of unmyelinated and thinly myelinated nerve fibers. Aδ fibers are responsible for transmitting sharp, localized pain and temperature sensations, while C-fibers transmit dull, diffuse pain and temperature sensations. The Aδ fibers have a faster conduction velocity compared to C-fibers, which allows for the rapid transmission of touch and pressure sensations. The activation of mechanoreceptors in the skin, such as Meissner's corpuscles and Pacinian corpuscles, triggers the release of neurotransmitters that stimulate the Aδ fibers, leading to the perception of touch.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a distractor. While A-fibers do transmit sensory information, they are not responsible for transmitting touch sensations.
**Option B:** This option is incorrect because it is a distractor. While C-fibers do transmit pain and temperature sensations, they are not the primary nerve fibers responsible for transmitting touch sensations.
**Option C:** This option is incorrect because it is a distractor. While Aβ fibers do transmit sensory information, they are primarily responsible for transmitting proprioception and vibration sensations, not touch.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the types of nerve fibers responsible for transmitting different sensory modalities can be affected by various pathologies, such as peripheral neuropathy or nerve damage, leading to altered sensation or loss of sensation.

**Correct Answer: C. A-delta and C-fibers are responsible for transmitting touch sensations.
