The correct answer is: Only 1 & 2.
Railway Creeper (Clematis vitalba) is an invasive species of plant found in India. It is a fast-growing vine that can smother native vegetation. Lantana camara is another invasive plant species found in India. It is a shrub or small tree that can form dense thickets that outcompete native plants. Black wattle (Acacia mearnsii) is a tree that is native to Australia but has been introduced to India. It is an invasive species that can outcompete native plants and alter the ecosystem.
The other options are incorrect because they include species that are not invasive in India.
