(A) Installment option. The assessment shall be due and payable within 30 days after final publication of the assessing ordinance without demand except that all assessments at the election of the owner may be paid in installments.
(B) Installments automatic unless paid in full. Failure to pay the whole assessment within said 30 days shall be conclusively considered and held to be an election on the part of the persons interested, whether under disability or not, to pay in such installments. All persons so electing to pay in installments shall be conclusively held and considered as consenting to said improvements and such election shall be conclusively held and considered as a waiver of any right to question the power or jurisdiction of the municipality to construct the improvement, the quality of work, the regularity or sufficiency of the proceedings, or the validity or the correctness of the assessments or the validity of the lien therefor.
