Explanation:

• The Constituent Assembly of India was formed in December 1946 having 389 representatives and later this number was reduced to 299. Out of these 299 members, 15 members were women.
• The women members of the Constituent Assembly were Ammu Swaminathan, Dakshayani Velayudhan, Begum Aizaz Rasul, Durgabai Deshmukh, Hansa Mehta, Kamla Chaudhary, Leela Roy, Malati Choudhury, Purnima Banerjee, Rajkumari Amrit Kaur, Renuka Ray, Sarojini Naidu, Sucheta Kriplani, Vijaya Lakshmi Pandit and Annie Mascarene. • Begum Aizaz Rasul was the only Muslim woman member of the Constituent Assembly.
• Dakshayani Velayudhan was the first and only Dalit woman to be elected to the constituent assembly in 1946.
• Annie Mascarene was born into a Latin Catholic family in Thiruvananthapuram, Kerala. She was the first woman to be part of the Travancore State Congress Working Committee.
•  Sucheta Kriplani sang Vande Mataram in the Independence Session of the Constituent Assembly. She was also India’s first woman Chief Minister.
• Thus, Usha Mehta and Captain Lakshmi Sahgal were not members of the assembly. Lakshmi Sahgal was the daughter of Ammu Swaminathan and she lead the Rani Jhansi regiment in the Indian National Army under Subhash Chandra Bose. • Hence option (b) is the correct answer.
