(D) Manganese toxicity is a condition in plants caused by an excess of manganese,characterized by the following effects:$1$. The appearance of brown spots surrounded by chlorotic veins.$2$. Manganese competes with iron and magnesium for uptake and binding with enzymes.$3$. Manganese inhibits calcium translocation to the shoot apex.$4$. Consequently,an excess of manganese may induce deficiencies of iron,magnesium,and calcium.Thus,the symptoms observed as manganese toxicity are often the deficiency symptoms of iron,magnesium,and calcium.
