The correct answer is: A. 5 partners.
An ordinary partnership firm can have a maximum of 5 partners. This is because the Indian Partnership Act, 1932, states that “Every partnership shall consist of at least two and not more than twenty persons.”
The Act also states that “Where a partnership consists of more than ten persons, every person who is a partner in the firm at the time of the registration of the firm shall be liable to pay to the Registrar a fee of one hundred rupees for every person in excess of ten.”
Therefore, the maximum number of partners in an ordinary partnership firm is 5.
Option B is incorrect because the Indian Partnership Act, 1932, states that “Every partnership shall consist of at least two and not more than twenty persons.”
Option C is incorrect because the Indian Partnership Act, 1932, states that “Every partnership shall consist of at least two and not more than twenty persons.”
Option D is incorrect because the Indian Partnership Act, 1932, states that “Every partnership shall consist of at least two and not more than twenty persons.”
