Option: b. had little or no knowledge of sterilization.

Explanation:

Medical practitioners during the 17th century and 18th century had very little knowledge about the sterilization. Sterilization was little known during this period because practitioners were still learning how to treat people and did not give priority to sterilizing. Sterilizing the surgical instruments was not much in a process. It became increasing use in the late 18th century.
