**Core Concept**
The "five cleans" refer to a set of practices aimed at reducing the risk of sepsis at birth, particularly in low-resource settings. These include clean delivery surface, clean delivery attendant, clean birth attendant's hands, clean blade or other cutting instrument, and clean cord tie.

**Why the Correct Answer is Right**
The "five cleans" are essential in preventing sepsis at birth by reducing the transmission of pathogens from the environment, birth attendant, and mother to the newborn. Clean delivery surfaces, birth attendants, and hands minimize the risk of bacterial contamination. Clean cutting instruments and cord ties prevent the spread of infections such as tetanus and neonatal sepsis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not specified, so we'll proceed to the actual options provided.
**Option B:** Not a part of the "five cleans," but rather an essential component of newborn care and prevention of neonatal tetanus.
**Option C:** Not included in the "five cleans" as it is a separate measure to prevent neonatal tetanus.
**Option D:** Not specified, so we'll assume the actual options provided will be the correct ones to address.

**Clinical Pearl / High-Yield Fact**
The "five cleans" can be remembered using the mnemonic "CLAMS": Clean delivery surface, Clean delivery attendant, Clean birth attendant's hands, Clean blade or other cutting instrument, and Clean cord tie.

**Correct Answer: B. Not a part of the "five cleans," but rather an essential component of newborn care and prevention of neonatal tetanus.**
