Best answer
Right choice is (b) false

The best I can explain: The first two members are gases, the next eight members are liquids and higher members are solids. Alkynes are colourless and odourless with the exception of acetylene, which has slightly garlic or due to the presence of phosphine gas and hydrogen sulphide gas.
