Given information
In an acid-base titration, the equivalence point is the point at which moles of acid and moles of the base are equal.
Step-by-step explanation
Step 1.
Reason for correct answer:
The option (a), that is all three solutions require the same volume of 
to reach the first equivalence point is true because the stoichiometric ratio to attain the first equivalence point stays the same for 
, 
and 
.
Molarity of all the acids is 
Molarity of is 
The moles and volume of all the acids are the same as the moles and volume of at the first equivalence point.
Therefore, the stoichiometric ratio is the same for all acids and bases, .
