The answer is the third one (c): forced uplift due to the presence of a physical barrier.

Explanation for each option:

a. Convection stimulated principally by local heating: This describes convective lifting, which occurs when the ground heats the air above it, causing the air to rise. This is not related to orographic lifting.

b. Lifting along the edges of conflicting air masses: This describes frontal lifting, which occurs when two different air masses meet, and one is forced to rise over the other. This is not related to orographic lifting.

c. Forced uplift due to the presence of a physical barrier: This is the correct definition of orographic lifting. It occurs when an air mass is forced to rise over a mountain range or other physical barrier, leading to cooling and often precipitation on the windward side of the barrier.

d. None of the above: This option is incorrect because option c accurately describes orographic lifting.

In summary, orographic lifting is the process of air being forced to rise due to a physical barrier, such as a mountain range.

Magnesium sulfat merupakan senyawa yang memiliki peran penting bagi kesehatan tubuh. Magnesium sulfat berperan dalam menjaga kesehatan sel, saraf, sistem imun, denyut jantung, tulang dan fungsi kerja otot. Setiap manusia memiliki kadar minimal magnesium sulfat, seper pada balita ( <5 tahun) memiliki nilai minimal 200 gram, untuk remaja (usia 6-19 tahun) kadar minimal magnesium sulfat 300 gram, sedangkan untuk dewasa (usia 20-40 tahun) kadar minimal magnesium sulfat 350 gram. Data pasien yang mengalami kekurangan magnesium sulfat dari salah satu rumah sakit di kota X adalah sebagai berikut. Nama Usia (tahun) Kadar Magnesium Sulfat (gram) Pasien 1 4 80 Pasien 2 14 240 Pasien 3 33 230 Pasien 4 21 290 Pasien 5 25 338 (ArMg=24 ; S=32 ; O=16) 1.
