SQLite database crashes app

Question

I'm running a database in my app and it suddenly began to crash my app after working before. i changed it to try to add in a second table which crashes the app but when i reverted it back to the working version the app still crashes. i'm not sure why. here is the code

DBHelper

public class DBHelper extends  SQLiteOpenHelper
{
public DBHelper(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "triviaQuiz";
// tasks table name
private static final String TABLE_QUEST = "quest";
// tasks Table Columns names
private static final String KEY_ID = "id";
private static final String KEY_QUES = "question";

private static final String KEY_ANSWER = "answer"; //correct option
private static final String KEY_OPTA= "opta"; //option a
private static final String KEY_OPTB= "optb"; //option b
private static final String KEY_OPTC= "optc"; //option c
private SQLiteDatabase dbase;

+ " TEXT, " + KEY_ANSWER+ " TEXT, "+KEY_OPTA +" TEXT, "
+KEY_OPTB +" TEXT, "+KEY_OPTC+" TEXT)";
db.execSQL(sql);
addQuestions();

//db.close();
}

{
    Question q1=new Question("8 X 2 " + "=","16", "20", "18", "C");
    this.addQuestion(q1);
