The Constituent Assembly held its first meeting on December 9, 1946. The Muslim League boycotted the meeting and insisted on a separate state of Pakistan. The meeting was, thus, attended by only 211 members. Dr. Sachchidananda Sinha, the oldest member, was elected as the temporary/provisional President of the Assembly, following the French practice. Later, Dr. Rajendra Prasad was elected as the President of the Assembly. Hence, option (d) is the correct answer.
