Option a is wrong because yeast does not convert sugar into lactic acid.

Ans 2:

Class : Class 8
I think that option A and C should be correct. Since option A talks about fermentation occuring which could be true considering that yeast is put into warm sugar solution. Option C is also correct since we know that one of the end products of fermentation is CO2 and lime water turns milky white when it is combined with carbon-dioxide.

Ans 3:

Class : Class 8
answer cant be A since during fermentation of sugar alcohol is produced and not lactic acid

Ans 4:

Class : Class 8
Then option A should also be correct as it talks about fermentation

Ans 5:

Class : Class 8
Option C is the correct answer because yeast causes fermentation .Fermentation is an anaerobic process. In this process yeast converts sugar into alcohol and carbon dioxide. Lime water turns milky indicating the presence of carbon dioxide.
