Since this is a pure definitional recall question, the fastest approach is to recall what each cited clause of Section 2 actually defines and see which one matches Bailable Offence.
Matching the question's term against the Code's own glossary shows that Section 2(a) alone supplies the definition being asked for.
The clause most often confused with the definition of a bailable offence is Section 2(c), because cognizable and bailable classifications sit side by side in the First Schedule and students frequently mix up which clause defines which term. Setting the two side by side resolves the confusion.
Once the cognizable-offence definition in Section 2(c) is separated from the bailable-offence definition in Section 2(a), and the two unrelated clauses are set aside, Section 2(a) is confirmed as the provision defining a bailable offence.
Therefore, the correct answer is Section 2(a).
