The inflorescences with indeterminate growth of axis are found in
The inflorescences with indeterminate growth of axis are found in Raceme and cyathium. Indeterminate simple inflorescences are generally called as racemose. The main kind of racemose inflorescence is the raceme and the other kind of racemose inflorescences can all be derived from this one by dilation, compression, swelling or reduction of the different axes. The cyathia are sometimes solitary, but are usually in cymes, inflorescences of the second order, in pseudumbels, on dichotomously branched stalks or in so-called simple cymes which consist of one central and two lateral cyathia.
Therefore, the correct answer is option A.
