Nominal share capital is :

Nominal Share Capital is the same as Authorized Capital or Registered Capital.

This represents the maximum limit of share capital that a company can issue to shareholders. This limit is mentioned in the Capital Clause of the company's Memorandum of Association at the time of incorporation.

For example, if a company states in its MOA that its authorized capital is ₹10,00,000 divided into 1,00,000 shares of ₹10 each, then ₹10,00,000 is the nominal/authorized capital. The company cannot issue shares beyond this amount unless it increases its authorized capital through proper legal procedure.

Let's understand why other options are incorrect:

Option 1 describes Issued Capital - the portion of authorized capital that the company actually offers for subscription to the public.

Option 2 describes Subscribed Capital - the portion of issued capital that investors actually apply for and get allotted.

Option 4 describes Paid-up Capital - the actual amount paid by shareholders against their allotted shares.

The relationship between these can be shown as:

Authorized Capital ≥ Issued Capital ≥ Subscribed Capital ≥ Called-up Capital ≥ Paid-up Capital

Therefore, Option 3 correctly defines Nominal Share Capital as the maximum amount a company is authorized to issue.
