SAGOT TIME!
1. The if-clause in a conditional statement (if-then statement) is the hypothesis (C). Basta may if, hypothesis na eun.
2. On the other hand, the then-clause is called conclusion (B). Basta may then, conclusion agad.
3. Letter B is not true because q should be the then-clause, not if-clause. p ang hypothesis o if-clause, q ang conclusion o then-clause.
4. Letter A is the hypothesis. Kapag hypothesis ang hinahanap, isama si if kasama ang kasunod niya.
5. Letter D is the correct statement.
