Hint:
The outermost whorl of the flower that constitutes sepals is known as calyx. Generally sepals are green leaf like and they protect the flower in bud stage . The calyx may be gamosepalous(sepals remain united) and polysepalous ( when sepals remain free). The portion of the calyx which remains with the fruit when fruit gets matured is termed as persistent calyx.
Complete answer:
> Allium / Liliaceae:- In this family calyx and corolla get fused to form perianth . They possess valvate aestivation . So calyx is not persistent in them. Hence this option is not correct.
> Hibiscus/ Malvaceae:- calyx are 5 usually separate. The calyx does not remain attached with fruit. So the option is not correct.
> Dalbergia/papilionatae:- it has a gamosepalous condition but not persistent calyx. The calyx of this may be equal and unequal. This option is not correct.
> Solanum/solanaceae :- the calyx have a gamosepalous condition . They have persistent calyx and show valvate aestivation. So this option is correct.
Our correct answer is d) that is Solanum/solanaceae.
