Multibacillary Leprosy refers to a person with:

• Paucibacillary (PB) Leprosy:

  • Has 1–5 skin lesions

  • Single or no nerve involvement

  • Skin smear negative for Mycobacterium leprae

• Multibacillary (MB) Leprosy:

  • Has more than 6 skin lesions

  • More than one nerve involvement

  • Skin smear positive for acid-fast bacilli

  • Indicates high bacterial load and greater infectivity

Therefore, in multibacillary leprosy, both multiple lesions and multiple nerve involvement are present — hence the correct answer is: More than 6 skin lesions with more than one nerve involvement.
