Step-by-step explanation

The range of bacteria or other microorganisms that are affected by a certain antibiotic is expressed as its spectrum of action. Antibiotics which kill or inhibit a wide range of Gram-positive and Gram-negative bacteria are said to be broad spectrum antibiotics. Those effective mainly against Gram-positive or Gram-negative bacteria are narrow spectrum antibiotics.

Salvarsan is an antibacterial drug.-As=As-linkage present in arsphenamine or Salvarsan

Penicillin G is a narrow spectrum antibiotic

Ofloxacin is an important broad spectrum antibiotic.

Terpineol along with chloroxylenol are the components of dettol  which is used as antiseptic .

Hence, Ofloxacin is the only broad spectrum antibiotic among the given options.
