(1) Both the statements are true
(2) Both the statements are false
(3) Statement-1 is true and statement-2 is false
(4) Statement-1 is false and statement-2 is true

Answer 1

Hey there!!
CO2 is soluble because water molecules are attracted to these polar areas.
And carbon monoxide has higher affinity than oxygen...
So 1st is false.. n i cant surely say abt 2nd stmnt..
Sorry fr the inconvinience... hope this much helped

Answer 2

correct answer is option no 4 that is statement no 1 is incorrect and statement 2 is true;
