The correct options are
A Once the election is complete, the Election Commission counts the votes.
B If a single party does not secure a majority, it can form a coalition government with other parties.
C In case of any suspicion of electoral fraud or malpractice, the case can be taken to court.
Once the election is complete, the Election Commission counts the votes and declares the winner from each constituency. If a party doesn't get more than 50 per cent votes, it can form a coalition government with other parties. If a candidate feels that the winner has won the elections illegally, he or she can challenge it in the court, and the court can cancel the election if found that he or she has won the election through illegal means.
