Explanation:

• The code comes into force on the announcement of the poll schedule and remains operational till the process is concluded, as provided in the notification. It is also applicable to a “caretaker” government on premature dissolution of a State Assembly, as was the case in Telangana.
• According to the EC, the code states that the party in power — whether at the Centre or in the States — should ensure that it does not use its official position for campaigning. Ministers and other government authorities cannot announce financial grants in any for No project or scheme which may have the effect of influencing the voter in favour of the party in power can be announced, and Ministers cannot use official machinery for campaign purposes.

Hence all statements are correct.
