\mathrm{ \frac{\mathrm{T}_{\mathrm{s}}^2}{\mathrm{~T}_{\mathrm{e}}^2}=\frac{\left(\frac{\mathrm{a}}{2}\right)^3}{(\mathrm{a})^3}=\frac{1}{8} ; \frac{\mathrm{T}_{\mathrm{s}}}{\mathrm{T}_{\mathrm{e}}}=\frac{1}{\sqrt{8}} }

\mathrm{ \mathrm{~T}_{\mathrm{s}}=\frac{\mathrm{T}_{\mathrm{e}}}{\sqrt{8}}=\frac{365}{2 \sqrt{2}}=129 \text { days } }

Hence option 4 is correct.
