Article 19(1)(c) guarantees the Right to form associations or unions. However, the Supreme Court has consistently held that the Right to Strike and Right to Lockout are NOT fundamental rights. These are statutory rights created by industrial laws, not inherent in the right to form association. Right to collective bargaining is also a statutory right, not a fundamental right under Article 19. Therefore, 'None of these' is the correct answer as none of A, B, or C are constitutionally guaranteed rights.
