Applicability of Section 54 or 54F

I have sold [12 years after the purchase] a residential plot which is there in gated community and I understand it is part of LTCG. Since it is a residential plot [no house constructed] should the income tax be claimed under which of the following.

1) Section 54 [Hope I can invest in Two Houses and also 54EC Bonds & Here Capital gain is based on Indexation]

2) Section 54F [Hope this allows to invest in Only one house and 54EC bonds & Here capital gain on full consideration]

There are different articles defining residential land as also house property. Please clarify.

Thanks in advance
