The scenario involves a personal service contract containing both a positive obligation, to perform exclusively for the company, and a negative obligation, not to perform for anyone else, so the analysis under the Specific Relief Act, 1963 must treat these two obligations separately.
Because the negative promise not to perform elsewhere is distinct and enforceable even though the positive promise to perform cannot be, the injunction restraining Ajeet Singh from singing for the rival company is the appropriate relief.
Hence, the correct answer is The injunction may be granted to enforce the negative covenant.
