Exp) Option a is the correct answer

In case of the death of a candidate before poll, the Election Commission countermands the election only in case of recognized political party. It has no obligation to countermand an election on the death of candidate of a registered political party or an independent candidate. As per the Section 52 (1) of the RoPA 1951, the Returning officer (RO) after receiving report of death of a candidate of recognized political party shall announce the order for the adjournment of the poll/countermanding the poll. Further, the date of poll has to be notified later. The Report of the countermanding the election has to be produced to the Election Commission. Then the ECI, call upon the recognized political party to nominate another candidate for the said poll within a period of 7days of the issue of such notice.
