Answer 1

I think (a) apueous glutaraldehyde for 10 hours

Answer 2

Solution:

100°C boiling water for 30 minutes method will not sterilize.

Explanation:

Sterilization is a process by which an article, surface, or medium is made germ or microbes free.

There are various chemical and physical methods to sterilize objects.

Here are some of the sterilization methods:

• Aqueous glutaraldehyde for 10 hours
• Dry heat at 171°C for 1 to 2 hours
• 121°C at 15 lb/in pressure for 15 to 20 minutes

Hence, option d is correct as 100°C boiling water for 30 minutes is not the sterilization method.
