Which of the following is/are the features of basic lava?

Rich in iron and magnesium

Have low fluidity

Common along the constructive boundaries

Generally, forms composite volcanoes

Choose the correct answer using the codes given below:

Question

Basic lavas are the hottest lavs, about 1,000 °C and are highly fluid.
They are dark coloured basalt, rich in iron and magnesium but poor in silica.
They flow out of volcanic vent quietly and are not very explosive.
Due to their high fluidity, they flow readily with a speed of 10 to 30 miles per hour.
They affect extensive areas, spreading out as thin sheets over great distances before they solidify.
The resultant volcano is gently sloping with a wide diameter and forms a flattened shield or dome.
Most shield volcanoesare formed from fluid, basaltic lava flows. Mauna Kea and Mauna Loa are shield volcanoes.
Shield type lava flow is common along the constructive boundaries (divergent boundary).
