Explanation:

Let’s break it down:

- Disinvestment basically means the government is selling its stake in a public sector enterprise.

- Option 1: Private enterprises — Yeah, this is what disinvestment is all about. The government sells assets it owns to private players, moving things from public to private hands.

- Option 2: Public enterprises — That would just mean transferring within government-owned companies, which isn’t really disinvestment.

- Option 3: Capital market — Sometimes shares are sold here, but capital market isn’t an owner, it’s a platform.

- Option 4: Departmental enterprises — This refers to government-run segments, not external buyers.

So, the answer is clear—public investments are sold to private enterprises.
