Study the given flow chart carefully and answer the question.
Which group lists the items that can replace R in the flow chart?



                 P                          Q                        R
AIce cube              Oxygen             Cold Drink
BOxygen                Hydrogen           Water Vapour
CCoca cola               Milk                  Vinegar
DWater Vapour       Oxygen                 Milk


How can the answer be option B? Gases do not have definite shape or volume. Therefore P cannot be oxygen and Q cannot be Hydrogen. Pls clarify

The question is which can replace R. according to the flow chart /r doesn't have definite shape nor volume. So it should be a gas or vapour. the option B has all the items in the form of gas, oxygen, hydrogen and watervapour and is the right answer.

Ans 2:

Class : Class 3
The group listing items that can replace R is Option B. The marking P Q R above the options is an error which we regret and will correct as soon as possible. Thanks for bringing it to our notice.
