Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- Statement A is correct: Non-chordates like invertebrates often have a pharynx perforated by gill slits.
- Statement B is correct: Non-chordates lack a notochord.
- Statement C is correct: The central nervous system in non-chordates is dorsal.
- Statement D is correct: In non-chordates, if a heart is present, it is usually dorsal.
- Statement E is incorrect: Many non-chordates possess a post-anal tail.
Thus, the correct answer is: B, D, and E only.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
